When I masturbate, I usually grab the foreskin and move it back and forth. I sometimes move the fingers directly on the glans but it's a bit rough and irritating.
I'm curious - how do circumcised males do it? No contact with glans? Or contact with glans but lots of lubrication? (if so, what kind: saliva? KY jelly?) Or contact with glans and irritation?
Isn't it difficult?
(Note: this is not a society debate on circumcision, just a factual question on masturbation techniques and difficulties.)
