Rainbow Kiss: Why Couples Mix Period Blood & Cum (And Love It)

This Practice Has Couples Either Obsessed or Horrified

Look, we are not going to sugarcoat this – rainbow kiss isn’t for everyone. But for the couples who’ve tried it? Many describe it as one of the most intensely bonding experiences they’ve shared. There’s something about crossing that particular line together that creates a level of trust and acceptance most relationships never reach.

You know that moment in a relationship when you realize your partner truly sees all of you – the Instagram-worthy parts and the “please don’t look at me right now” moments? Rainbow kisses are like that realization on steroids, wrapped in controversy, and served with a side of “did we really just do that?”

Here at BSP, we’ve heard from couples who swear this practice cracked open a whole new level of intimacy they didn’t know existed. We’ve also heard from plenty who tried it once and immediately switched to discussing weekend brunch plans. Both reactions are perfectly valid – not every adventure needs to become a regular Tuesday tradition.

What Rainbow Kisses Actually Are (Spoiler: It’s Not About Skittles)

Strip away the shock factor, and here’s the deal: during menstruation, partners give each other oral pleasure, then kiss while still holding those combined fluids in their mouths. The mixing of period blood and semen creates that reddish-white combination some folks dubbed a “rainbow” – though honestly, it looks more like abstract art than anything you’d see after a storm.

But here’s where it gets psychologically juicy – you’re literally sharing the most intimate parts of yourselves during a time society labels as “dirty.” When someone looks at your period blood the same way they look at your regular arousal? That’s relationship-changing territory right there.

The couples who get hooked on rainbow kisses often describe it as their ultimate “ride or die” litmus test. It’s like that Taylor Swift lyric about loving someone through their “golden” and their “dark” moments – except way more literal and involving significantly more bodily fluids. There’s something beautifully rebellious about giving society’s menstrual taboos the middle finger through pure intimacy.

Like other adventurous oral experiences such as bukkake scenarios, rainbow kisses demand serious trust, communication, and a shared sense of adventure. This isn’t “let’s try something wild on a whim” territory – it’s more “we trust each other with our deepest vulnerabilities” energy.

Safety Talk: Keeping Things Hot AND Healthy

Before we dive into the steamy details, let’s talk real-world health facts – because the best adventures keep everyone safe and satisfied.

When the Green Light Is Actually Green:

• Both of you have recent, clean STI test results (we’re talking within the last 3-6 months)
• The menstruating partner’s flow is normal – no funky colors, smells, or textures that scream “something’s off”
• Nobody’s got mouth cuts, recent dental work, or gums that bleed when you brush
• You’re both genuinely curious, not just trying to one-up your last Tinder date’s story

When to Pump the Brakes Hard:

• Any STIs in the mix (blood contact is like rolling dice with higher stakes)
• Unusual discharge, odor, or anything that makes you go “hmm, that’s new”
• Recent mouth injuries, dental surgery, or bleeding gums
• One person’s doing this to “prove” the relationship while the other’s internally screaming “nope”

Your Safety Game Plan:

• Schedule this adventure for lighter flow days – think days 2-4 when things are manageable
• Keep that mouthwash handy (but wait 30 minutes after to avoid mouth irritation)
• Stock up on dark towels, tissues, and water bottles for easy cleanup
• Plan a cozy shower together afterward – it’s practical AND romantic

Here’s the real talk from our research: couples who practice this safely treat it like any other fluid-exchange activity. Research on intimate boundary-crossing shows that couples who successfully navigate taboo practices prioritize communication and mutual enthusiasm above all else. This isn’t a spontaneous “heat of the moment” thing – it requires the same preparation you’d give any intimate adventure that involves bodily fluids. Understanding fluid bonding safety principles can help you approach rainbow kisses with the right mindset and precautions.

Having “The Conversation” Without Sounding Like You’ve Lost Your Mind

Bringing up rainbow kisses is often trickier than actually doing them. Here’s how to float this idea without your partner immediately googling “how to change your identity and move to another state”:

Start with the Foundation: “You know how comfortable we are with period sex? It made me curious about exploring that acceptance even deeper. Have you ever thought about really embracing all the natural parts of our bodies?”

Test the Waters: “So, there’s this thing called rainbow kisses that some couples try… and before you give me that look, hear me out. It’s basically about showing ultimate acceptance of each other’s natural functions.”

Get Specific (But Gentle): “It involves oral pleasure during menstruation, then kissing with the fluids still in our mouths. I know it sounds intense, but something about the trust involved really intrigues me. What’s your gut reaction?”

Address the Elephant Immediately:

• Own that it sounds wild at first glance
• Emphasize this is about connection, not shock value
• Make it crystal clear there’s zero pressure and complete veto power
• Discuss safety like the responsible adults you are

The magic formula? Present this as an intimate adventure you’d love to share, not some relationship test you both need to pass. The 69 position creates the perfect setup for more adventurous oral play, including techniques like rainbow kisses when both partners are genuinely excited to explore together.

Your Step-by-Step Guide to Rainbow Kiss Territory

If you’ve both decided to take the plunge, here’s your roadmap for navigating first-time rainbow kiss waters:

The Pre-Game Setup:

1. Choose a lighter flow day (usually days 2-4 work best for beginners)
2. Both of you shower and handle oral hygiene like you’re about to meet the Queen
3. Transform your space with dark towels and keep cleanup supplies within grabbing distance
4. Establish a clear “pause” signal for anyone who needs to tap out

The Main Event:

1. Start with plenty of foreplay – arousal makes everything better and more comfortable
2. Begin with the non-menstruating partner giving oral pleasure first
3. They keep their partner’s essence in their mouth without swallowing
4. Switch positions for the menstruating partner to return the favor
5. They hold the menstrual fluids in their mouth during oral play
6. Come together for the kiss while both still have fluids present
7. Let everything mix naturally during your kiss
8. Decide together whether to swallow or spit (both choices are totally valid)

The Immediate Aftermath:

• Resist the urge to immediately rinse – stay present with each other
• Share your real-time reactions while everything’s fresh
• Head to the shower together for intimate cleanup time
• Process whatever emotions pop up (they might surprise you)

Here’s what we’ve learned from couples who’ve tried this: the actual physical moment often feels surprisingly tender despite its intensity. The psychological rush of sharing something so taboo frequently creates an emotional high that’s completely different from regular sexual experiences.

Setting the Stage: Your Rainbow Kiss Toolkit

Must-Have Supplies:

• Dark towels in burgundy or black (your laundry will thank you)
• Soft tissues or gentle baby wipes for immediate touch-ups
• Water bottles for quick rinsing if needed
• Alcohol-free mouthwash (regular stuff can sting after oral play)
• Fresh sheets ready to go for your post-adventure snuggle session

Comfort Upgrades:

• Waterproof mattress protector for total peace of mind
• Dim, warm lighting that feels romantic rather than clinical
• Your favorite chill playlist to maintain relaxed vibes
• Fluffy robes for the graceful transition to shower time

Environment Goals: You want this space to feel sacred and special, not like a crime scene investigation. Think romantic rebellion against societal norms, not medical procedure. The vibe should whisper “we’re doing something beautifully taboo together” rather than “let’s get this over with.”

When Reality Doesn’t Match Instagram Expectations

“Holy hell, this tastes way more intense than expected” Keep water within arm’s reach for immediate dilution if the metallic flavor hits harder than anticipated. Some folks find period blood more pronounced than they imagined – totally normal and not a failure on anyone’s part.

“One of us is having a moment mid-experience” Hit that pause button immediately, no questions asked. There’s zero shame in discovering something isn’t your jam once you’re in the thick of it. Emotional reactions can blindside you with this kind of intensity.

“We’re both theoretically into this but practically it’s feeling awkward” Slow your roll and build up gradually. Try period-positive activities like shower sex during menstruation first. Get comfortable with blood contact before jumping into the deep end of rainbow kiss territory.

“There’s an enthusiasm mismatch happening” Never, ever proceed unless both people are genuinely excited. Reluctant participation kills the very intimacy this practice is designed to create. Enthusiastic consent isn’t just about safety – it’s about creating something beautiful together.

Who Gets Absolutely Hooked on This Taboo Adventure

Rainbow kisses tend to click with couples who:

• Already rock period sex without any shame or “ew” faces
• Get turned on by pushing boundaries together as relationship bonding
• Find that breaking social taboos actually increases their connection
• Want to demonstrate complete acceptance of natural body functions
• Are genuinely curious about practices that flip off menstrual stigma

This definitely isn’t everyone’s cup of tea, and that exclusivity is exactly what makes it powerful for some relationships. If you’re drawn to practices that challenge social norms and push intimate boundaries together, there are plenty of other adventurous territories worth exploring when you’re both ready to deepen that connection

The Post-Rainbow Reality Check

Physically Speaking: Expect that metallic taste to linger even after mouthwash does its thing. Some people report mild tummy sensitivity if they swallow everything, though serious reactions are pretty rare when you follow basic health precautions.

The Emotional Rollercoaster: Many couples experience this intense bonding rush followed by a processing period where they’re like “whoa, we really just shared that.” This emotional intensity is completely normal and often strengthens relationship intimacy for the long haul.

Relationship Shift: Couples who try rainbow kisses together frequently report feeling like they’ve entered “no secrets” territory where shame around natural body functions just evaporates completely.

Future Adventures: Some couples make this a monthly tradition, others try it once and feel satisfied with that experience, and plenty discover it’s absolutely not their thing. All of these outcomes are perfectly valid – there’s no “right” way to feel about this.

Why Some Couples Become Complete Rainbow Kiss Converts

For couples who embrace this practice, it often becomes symbolic of their willingness to love each other completely – beyond society’s ridiculous shame around natural body functions. It’s less about the physical mechanics and more about what it represents: unconditional acceptance of your partner’s body in every form it takes.

The intimacy created by sharing something considered so taboo frequently spills into other relationship areas. Couples tell us they feel more comfortable discussing anything, more accepting of each other’s human imperfections, and more willing to explore boundaries together across all aspects of their relationship.

If rainbow kisses spark your curiosity, start with honest conversations about period positivity and complete body acceptance. The physical act is just one expression of a deeper intimacy philosophy that can transform your entire connection – whether you ever try this particular adventure or stick to admiring the concept from afar.

Your Burning Rainbow Kiss Questions, Answered

Is this actually safe if we’re both healthy? With proper precautions – recent clean STI tests, no mouth injuries, normal menstrual health – the risks are manageable. However, menstrual blood does carry higher STI transmission potential than other bodily fluids, so testing isn’t optional here. Don’t even think about attempting this without recent, clean results from both partners.

What’s the actual taste situation we’re dealing with? Most couples describe it as intensely metallic with salty undertones from semen. The texture’s thicker than regular kissing, and the taste hangs around longer than you might expect. Some find it surprisingly mild, while others get hit with more intensity than they bargained for. It’s basically impossible to predict until you’re there.

How do we know if we’re actually ready for this adventure? You’re ready when both of you are genuinely curious (not just trying to impress each other), already comfortable with period intimacy, and can discuss it openly without cringing. If either person feels pressured or gets squeamish during the conversation, pump the brakes until mutual enthusiasm shows up.

What if we try it and immediately regret everything? Completely normal and nothing to beat yourselves up about. Plenty of couples try this once out of curiosity and decide it’s absolutely not their vibe – that’s totally valid. The beautiful thing is exploring new territory together, not necessarily loving every single destination you visit.

Should this become our new monthly ritual? Only if both of you genuinely love it, not just tolerate it for your partner’s sake. Some couples incorporate it into their regular cycle, others save it for special occasions, and many try it once and feel completely satisfied with that experience. Let your authentic preferences be your guide, not some idea of what “adventurous couples” should do.
