Step-by-Step Guide

1

The penetrating partner sits on a sturdy surface with feet flat on the floor, creating a stable base for the grinding motion that defines this position.

2

The receiving partner sits on the penetrating partner's lap facing away, lowering themselves onto the penis while their back rests against the penetrating partner's chest.

3

The receiving partner begins grinding in wide, circular motions — like an eraser on paper — pressing their clitoris against the pubic bone with each rotation.

4

Lean back slightly to shift the angle forward, increasing clitoral contact; lean forward to reduce pressure and focus on internal G-spot sensation instead.

5

The receiving partner controls the entire experience — speed, pressure, angle, and rhythm — while the penetrating partner provides the base and matches the energy.

6

The penetrating partner can reach around to caress the receiving partner's breasts or add manual clitoral stimulation to complement the grinding motion.

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 Eraser position:

Bouncing instead of grinding

Eraser is defined by its circular grinding motion. Bouncing up and down misses the sustained clitoral contact that creates the "erasing" sensation.

Sitting too upright without leaning

The receiving partner should experiment with leaning forward or back to find the angle that creates the most clitoral friction. Staying rigidly upright limits sensation.

The penetrating partner thrusting

This position puts the receiving partner in full control. The penetrating partner thrusting disrupts the grinding rhythm and takes control away from the person on top.

Neglecting the circular motion

The circular, erasing motion is what creates the unique clitoral stimulation. Moving only up and down turns it into a standard reverse cowgirl.

Variations to Try

Once you've mastered the basic Eraser, 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.
