Step-by-Step Guide
Both partners lie on their sides facing the same direction (spooning alignment), with the penetrating partner behind. The receiving partner's bottom leg stays straight; the top leg lifts and rests on the penetrating partner's hip — this leg position opens the vaginal canal from the side.
The receiving partner's top leg resting on the penetrating partner's hip is the key to this position — it controls the angle. Higher on the hip = steeper angle; lower on the hip = shallower angle. The receiving partner experiments to find the optimal placement.
Enter from the side-rear angle — the side alignment creates a slightly downward entry path along the anterior wall, targeting the G-spot. The bodies should form a straight line from heads to hips, with no twisting or misalignment.
Rock together in a slow, synchronized rhythm — both partners move their hips together. The side-lying position means neither partner bears weight, allowing for sustained, relaxed rhythmic movement without fatigue.
The penetrating partner can reach around to the receiving partner's front for clitoral stimulation — the side-lying position leaves the front accessible. The receiving partner can also guide the penetrating partner's hand to the right spot.
For deeper penetration, the receiving partner can pull their top leg back further toward their head, opening the angle more. For shallower, the leg can relax forward. This leg adjustment is the main control mechanism in this position.

Common Mistakes to Avoid
Even with the right technique, small errors can reduce pleasure or increase injury risk. Here are the most common mistakes couples make with the Straight Line position:
Top leg not resting on the penetrating partner's hip
If the top leg dangles passively or stays on the bed, you lose the angle control and the intimate leg-hook connection. The top leg MUST rest on the penetrating partner's hip to create the correct entry angle and maintain the aligned body contact.
Bodies misaligned along the same axis
Both partners must be on their sides in the same direction, with the penetrating partner's chest against the receiving partner's back. If the bodies are at different angles or the penetrating partner is positioned too high or low, the side-entry angle misses the intended stimulation zones.
Rushing the rhythm
The Straight Line is designed for slow, rhythmic movement — the name evokes patience and steady rhythm. Fast, energetic thrusting in a side-lying position is awkward and breaks the close body contact. Slow, rocking motions maintain the alignment.
Not adjusting the top leg for angle variation
The top leg's position on the hip is the main angle control — many couples don't realize they can shift the leg to target different internal areas. Experimenting with leg placement (higher, lower, forward, back) reveals different stimulation zones without changing anything else.
Variations to Try
Once you've mastered the basic Straight Line, these variations can add new sensations and keep things exciting:
Add a Pillow
Place a pillow under the receiving partner's hips to change the angle of penetration and enhance stimulation.
Incorporate Manual Stimulation
Use hands to add clitoral or other external stimulation during the position for enhanced pleasure.
Slow Down the Pace
Switch from thrusting to grinding for a more intimate, sensation-focused experience.
Try Different Surfaces
Move from the bed to a couch, standing, or against a wall for different angles and experiences.
