Step-by-Step Guide

1

The receiving partner lies on their stomach on a soft surface and props themselves up on their elbows, raising their hips by placing a pillow underneath — this is the sphinx pose.

2

The receiving partner should feel comfortable in the sphinx pose before attempting entry — if the elbows or lower back strain, add more pillow support under the hips.

3

The penetrating partner kneels behind and between the receiving partner's legs, aligning their pelvis with the raised hips.

4

Enter from behind at a slightly downward angle — the raised hip position creates a deep angle that targets the deep spot and anterior wall simultaneously.

5

The penetrating partner holds the receiving partner's hips for control, using their glutes to thrust while the receiving partner rests their upper body weight on their elbows.

6

Keep sessions brief as this Hard position demands core strength from the receiving partner. If the elbows tire, the receiving partner can lower to their chest temporarily.

  • ! Keep sessions brief to avoid fatigue.

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 Sphinx position:

Not raising the hips enough

Without sufficient hip elevation (from a pillow or blanket), the angle becomes too shallow and the deep spot stimulation is lost. The hips should be noticeably higher than the chest.

Putting weight on the receiving partner's lower back

The penetrating partner must support their own weight. Pressing down on the receiving partner's lower back can cause pain and spinal strain.

Ignoring elbow fatigue

The receiving partner's elbows will tire from supporting their upper body. Take breaks or use a folded towel under the elbows for cushioning.

Thrusting at the wrong angle

The sphinx creates a specific downward angle from behind. Thrusting horizontally misses the deep spot target zone entirely.

Variations to Try

Once you've mastered the basic Sphinx, these variations can add new sensations and keep things exciting:

1

Add a Pillow

Place a pillow under the receiving partner's hips to change the angle of penetration and enhance stimulation.

2

Incorporate Manual Stimulation

Use hands to add clitoral or other external stimulation during the position for enhanced pleasure.

3

Slow Down the Pace

Switch from thrusting to grinding for a more intimate, sensation-focused experience.

4

Try Different Surfaces

Move from the bed to a couch, standing, or against a wall for different angles and experiences.
