Side Sex Positions: 5 Most Comfortable Options

Quick Facts

What It Is: Intercourse performed with both partners lying on their sides, facing the same direction or face-to-face
Also Known As: Lateral positions, side-lying sex, spooning sex
Difficulty: Low — no weight-bearing on knees or wrists, minimal core engagement
Best For: Long sessions, pregnancy, recovery days, early mornings
Common Challenge: Maintaining depth and angle without losing rhythm

Side sex positions place both partners horizontal and lateral, distributing bodyweight along the mattress rather than concentrating it on knees or hips. The result is a family of configurations well-suited to sustained intimacy — the side position category spans spooning, face-to-face, and stacked variants, all sharing that low-strain foundation. This roundup focuses on the five most comfortable options and the specific mechanical reason each one works.

Spooning

Spooning is the reference position for the entire side-lying family. The rear partner curls behind the front partner, both facing the same direction, with entry from behind. The angle is slightly downward from the rear partner's perspective, which means the anterior wall of the vaginal canal receives consistent contact — the same zone targeted in positions designed for G-spot stimulation.

Movement is controlled by the rear partner's hip roll rather than full thrusting, which keeps depth moderate but friction high. The front partner can reach back to guide rhythm or adjust depth. For the numb-arm problem, see the FAQ below — a simple repositioning of the lower arm resolves it without interrupting anything.

Side Missionary

Side missionary flips the orientation so partners face each other, chest to chest. Entry angle shifts to a more anterior approach, broadly similar to classic missionary but without the weight-bearing. The gap between the partners' hips is smaller than in spooning, which means the penetrating partner can grind forward rather than thrust back-and-forth — that rocking motion maintains contact with the clitoris or pubic bone throughout.

Eye contact and kissing are straightforward in this position, which makes it a natural choice when the goal is connection alongside physical sensation. The top leg can be stacked or bent at the knee and rested on the partner's hip to open the angle slightly.

Lazy Dog

Lazy Dog is a side-lying adaptation of doggy style: both partners lie flat, the rear partner behind, but instead of the front partner being on all fours, both are horizontal. The entry angle is comparable to standing doggy but without the hip-height mismatch that can make standing variants awkward. Hip sockets stay neutral, and the front partner's lower back remains flat against the mattress — useful for anyone with lumbar sensitivity.

Depth in Lazy Dog tends to be slightly greater than in spooning because the front partner's hips can tilt back more freely. A pillow under the front partner's lower hip raises the pelvis a few centimetres and fine-tunes the entry angle without any repositioning.

Side 69

Side 69 is the lateral version of mutual oral sex. Both partners lie on their sides, heads at opposite ends, which splits bodyweight evenly and eliminates the common discomfort of the person on the bottom supporting the other's weight. Neck strain — the main complaint with top-or-bottom 69 — is significantly reduced because the head rests against the partner's inner thigh rather than being held up against gravity.

The trade-off is that coordination requires a little attention to maintain simultaneous rhythm, but the sustainable position makes longer sessions more feasible.

Bent Spoon

Bent Spoon is a hybrid: the rear partner lies flat while the front partner, instead of remaining on their side, rotates slightly upward to a semi-reclined position — somewhere between spooning and a seated rear-entry. The front partner's weight shifts forward onto their hands or elbows, and the change in hip angle produces a sharper upward tilt that increases anterior wall contact considerably compared to flat spooning.

This position suits partners with a noticeable height difference better than flat spooning, since the angular adjustment compensates for alignment gaps.

Side sex positions pair naturally with a pillow under the lower hip to maintain pelvic alignment and a water-based lubricant to compensate for the reduced natural lubrication that can occur in lateral positions where gravity pulls fluid away from the vaginal canal.

If low-effort positioning is the broader goal, the lazy sex positions guide covers positions across all orientations, not just side-lying. For pregnancy-specific guidance beyond the second trimester, the best sex positions for pregnancy page addresses weight distribution and vena cava avoidance in more detail.

The side-lying family works because it decouples physical comfort from access — you lose very little in terms of penetration or stimulation, and you gain a sustainable baseline that makes longer, more connected sessions achievable without the fatigue that interrupts them.

Frequently Asked Questions

What are side sex positions?

Side sex positions are any intercourse configuration where both partners lie on their sides — either facing the same direction (spooning) or face-to-face. The lateral alignment keeps body weight off the bottom partner, reduces hip-flexor demand, and produces a naturally angled entry that works well for sustained sessions.

Are side sex positions good during pregnancy?

Yes, especially from the second trimester onward. Lying on one side avoids supine pressure on the inferior vena cava, which can restrict blood flow when a pregnant person lies flat on their back. Spooning in particular lets the bump rest forward with no abdominal compression, making it one of the positions most commonly recommended for the third trimester.

How do you prevent a numb arm in spooning sex?

The classic numb-arm problem happens when the rear partner tucks their lower arm under the front partner's head. Instead, slide that arm forward so it rests along your own side or across the front partner's waist. A folded pillow under both heads equalises the height difference and takes pressure off the shoulder.

Can side sex positions produce deep penetration?

Depth is moderate by default — the lateral angle tends to shorten effective penetration compared to missionary. To increase it, the rear partner can draw their hips back slightly before thrusting forward, and the front partner can lift the top knee toward their chest. Even a small hip-tilt forward by the penetrating partner shifts the angle enough to reach deeper.

What is the difference between spooning sex and side missionary?

In spooning, both partners face the same direction so the rear partner enters from behind, creating a posterior angle. In side missionary, partners face each other and achieve a more anterior angle similar to classic missionary — eye contact and kissing are possible, and clitoral access is easier for manual stimulation.
