Can you play with a man's foreskin?

Yes, you can, and most men love it since the head and the foreskin are the most sensitive parts of the penis. The section where the mucous tissue changes to the skin that looks like the trunk of the penis is the most sensitive area on a mans body. this is the very end of the foreskin when the penis is soft. In fact, an uncircumcised male has more sensation in his penis than circumcised men, although, that does not necessarily mean he has more sexual pleasure.
