Below is an excerpt from a website article entitled Anatomy and Functions of the Male Foreskin
Found at: http://www.noharmm.org/anatomy.htm
“During masturbation, the mucosal surface of the foreskin rolls back and forth across the mucosal surface of the glans penis, providing nontraumatic sexual stimulation. During heterosexual activity, the mucosal surfaces of the glans penis and foreskin move back and forth across the mucosal surfaces of the labia and vagina, providing nontraumatic sexual stimulation of both male and female. This mucous-membrane-to-mucous-membrane contact provides the natural lubrication necessary for sexual relations and prevents both the dryness responsible for painful intercourse and the chafing and abrasions which allow entry of sexually transmitted diseases, both viral and bacterial.”
It took me a while (growing up) for me to realize what my intact foreskin afforded me in the sexual arena (weather by myself or with a partner) given the knowledge of what the foreskin does for me I can not imagine desiring to have it removed. For the longest time I wondered why many guys I knew would reference lubricants and lotions when speaking of (or joking about) masturbation…as if these things were synonymous with masturbating. I really didn’t understand why it was necessary to “lube up” before masturbating…I never required it, and I masturbate as much as the next guy (near as I could figure). I suppose it’s just another gift of being intact…the foreskin is truly functional.
