As a sex educator, I have spoken with thousands of women about their experience of intercourse with circumcised and uncircumcised men, and a clear pattern has emerged. It seems that circumcision not only effects male pleasure, it changes how they make love. Circumcised men tend to penetrate much more vigorously, in the jackhammer style that is so familiar from our cultural depiction of intercourse. This style of penetration comes from a desperate search for more stimulation and the need to concentrate sensations on the tip of the penis.

Uncircumcised men, on the other hand, often penetrate with more finesse, using a slower rhythm and more of an undulating motion. The intact foreskin acts as a sheath that glides over the penis with every thrust, creating more pleasure and reducing the need to thrust with as much force to create sensation
