Step-by-Step Guide

The penetrating partner sits on a sturdy surface with legs crossed in a comfortable, cross-legged position — like looking through clear glass at each other.

The receiving partner sits on the penetrating partner's lap, facing them, wrapping their legs around the penetrating partner's waist in a mirror image.

Lower yourself slowly onto the penis — the seated, cross-legged position creates a tight, intimate fit with medium depth.

Rock gently in slow circles rather than up and down — the grinding motion stimulates both the G-spot and clitoris through sustained contact.

Maintain unbroken eye contact throughout — the glass metaphor means complete transparency and visibility of every sensation and expression.

Use hands to caress each other's bodies, faces, and hair — the seated position frees both partners' hands for full-body exploration.

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 Glass position:

Bouncing instead of grinding

The cross-legged seated position is optimized for circular grinding motions. Bouncing up and down is unstable and misses the clitoral stimulation from the grinding contact.

Breaking eye contact

Glass is defined by complete visibility and transparency. Looking away or closing eyes removes the visual connection that makes this position intimate.

Sitting too far back on the surface

Both partners need to be close to the edge of the seat. Sitting too far back limits movement and makes entry difficult.

Forcing the cross-legged position

If either partner's knees are uncomfortable in the cross-legged position, modify by having one or both partners uncross their legs. Comfort comes first.
