Positions Guide
Evidence-based biomechanical analysis of sexual positions — clitoral stimulation potential, muscle engagement, caloric expenditure, injury risk, and clinical recommendations by medical condition.
Missionary & Face-to-Face
Classic Missionary
Partner on top, face-to-face. Penetrating partner supports weight on forearms.
Clitoral stimulation: Moderate — enhanced with coital alignment technique (CAT)
Depth control: Moderate — receiver can tilt pelvis to adjust
Muscles used: Core, shoulders, glutes, hip flexors (top); pelvic floor, hip flexors (bottom)
Calories burned: 150-200 cal/30min (top); 50-70 cal/30min (bottom)
Best for: Intimacy and eye contact, Beginners, Pregnancy (first trimester), Conception attempts
Caution: Top partner: wrist/forearm strain with prolonged support. Avoid in late pregnancy.
Lotus / Yab-Yum
Penetrating partner sits cross-legged; receiving partner sits in their lap, legs wrapped.
Clitoral stimulation: High — constant pelvic contact
Depth control: Moderate — shallow penetration, grinding motion
Muscles used: Core, hip flexors, quadriceps (both partners)
Calories burned: 100-150 cal/30min each
Best for: Maximum intimacy, Clitoral stimulation, Slow, connected sex, Tantric practice
Caution: Can be tiring for legs/hips. Not ideal for those with knee problems.
Rear-Entry
Doggy Style
Receiver on hands and knees; penetrating partner kneels behind.
Clitoral stimulation: Low — manual stimulation needed
Depth control: Deep — one of the deepest positions. Receiver controls by arching/flattening back.
Muscles used: Glutes, hip flexors, core (top); arms, core, quadriceps (bottom)
Calories burned: 150-250 cal/30min (top); 80-120 cal/30min (bottom)
Best for: Deep penetration, G-spot/P-spot stimulation, Partners with larger body types, Pregnancy (second trimester)
Caution: HIGHEST risk position for penile fracture. Cervical discomfort possible. Lower back strain for receiver.
Prone Bone
Receiver lies flat face-down; penetrating partner lies on top from behind.
Clitoral stimulation: Moderate — mattress/pillow provides indirect stimulation
Depth control: Shallow-moderate — tighter fit, reduced depth
Muscles used: Core, glutes (top); pelvic floor (bottom)
Calories burned: 100-150 cal/30min (top); minimal (bottom)
Best for: Tighter sensation, Lazy/low-energy sex, Those who find doggy too deep, Partners with back pain (receiver)
Caution: Top partner must support weight to avoid crushing. Limited depth may be frustrating for some.
Receiver on Top
Cowgirl
Receiver straddles penetrating partner face-to-face, controlling depth and rhythm.
Clitoral stimulation: High — receiver controls grinding angle for clitoral contact
Depth control: Full control — receiver sets depth and pace
Muscles used: Quadriceps, glutes, core, hip flexors (top); minimal (bottom)
Calories burned: 150-200 cal/30min (top); 50-80 cal/30min (bottom)
Best for: Female orgasm (highest probability position per studies), Receiver control, Partners with back pain (bottom), Pregnancy (all trimesters)
Caution: Quadriceps fatigue. Penile fracture risk if receiver lifts too high.
Reverse Cowgirl
Receiver faces away from penetrating partner while on top.
Clitoral stimulation: Low — different angle limits clitoral contact
Depth control: Full control by receiver — angle stimulates anterior wall
Muscles used: Quadriceps, glutes, core (top); minimal (bottom)
Calories burned: 150-200 cal/30min (top)
Best for: Visual stimulation, G-spot/P-spot stimulation angle, Variety
Caution: SECOND highest risk for penile fracture. Careful with extreme angles. Can strain penis downward.
Side-Lying / Spooning
Spooning
Both partners lie on same side, penetrating partner behind.
Clitoral stimulation: Low-moderate — hands free for manual stimulation
Depth control: Shallow — limited depth, gentle penetration
Muscles used: Minimal for both — very low energy
Calories burned: 50-100 cal/30min each
Best for: Morning sex, Pregnancy (all trimesters, especially third), Back pain, Post-surgery, Low energy / fatigue, Arthritis
Caution: May be difficult to maintain penetration. Limited depth.
Face-to-Face Side
Partners lie facing each other on their sides.
Clitoral stimulation: Moderate — close body contact
Depth control: Shallow-moderate
Muscles used: Minimal — intimate but low effort
Calories burned: 50-100 cal/30min
Best for: Intimacy, Pregnancy, Disability accommodations, Slow sex
Caution: Angle can be tricky. May need pillow support.
Seated
Lap / Chair
Penetrating partner sits on chair/edge of bed; receiver sits on top (facing toward or away).
Clitoral stimulation: High (facing) — pelvic grinding. Low (facing away).
Depth control: Moderate-deep — receiver controls
Muscles used: Core, quadriceps, glutes (receiver); minimal (seated partner)
Calories burned: 100-180 cal/30min (receiver)
Best for: Small spaces, Different surface heights, Mobility-limited seated partner, Wheelchair users
Caution: Chair stability important. Back support helps.
Standing
Standing Face-to-Face
Both partners standing, face-to-face. May require height adjustment or wall support.
Clitoral stimulation: Low-moderate — depends on alignment
Depth control: Limited — gravity and balance challenges
Muscles used: Quadriceps, calves, core, arms (both partners)
Calories burned: 200-300 cal/30min (both)
Best for: Quickies, Shower sex (with caution), Spontaneity
Caution: Height difference challenges. Slippery surfaces are dangerous. Most physically demanding category.
Recommendations by Medical Condition
Pregnancy (1st trimester)
Recommended: Missionary, Cowgirl, Side-lying
Avoid: None specifically — comfort is key
Pregnancy (2nd trimester)
Recommended: Cowgirl, Spooning, Doggy style, Side-lying
Avoid: Prolonged lying flat on back after 20 weeks (vena cava compression)
Pregnancy (3rd trimester)
Recommended: Spooning, Side-lying, Seated, Modified cowgirl
Avoid: Missionary (weight on belly), Flat on back (vena cava)
Lower Back Pain
Recommended: Spooning, Prone bone, Modified missionary (pillow under hips)
Avoid: Doggy style (if receiver), Missionary (if top partner)
Hip Replacement
Recommended: Missionary (bottom position), Spooning, Standing
Avoid: Positions requiring extreme hip flexion, adduction, or internal rotation
Arthritis
Recommended: Spooning, Side-lying, Supported seated
Avoid: Any position causing joint pain — listen to your body
Obesity
Recommended: Doggy style, Edge of bed, Cowgirl, Standing/bent over
Avoid: Missionary can be difficult with weight distribution
Erectile Difficulties
Recommended: Cowgirl (receiver maintains contact), Spooning (less performance pressure)
Avoid: Standing (gravity works against erection)
Conception Optimization
Recommended: Missionary, Doggy style, Elevated hips
Avoid: No scientific evidence any position prevents conception
