In pornos, I've seen that guys' foreskins usually stretch beyond the head of the guy's penis. I've also read in books that the foreskin stretches beyond the glans. That doesn't happen for me. It stretches, but only about half way down the glans. The head is never fully exposed.
I don't think I have a tight foreskin because I never feel any discomfirt during sex, masturbation or urination or at any other time. If anything, it maybe loose because, there is some extra skin at the tip. I can stretch the skin quite far off the head too. But it just seems to somehow be attached. It still doesn't seem to ristrict movement at all, because my dick has done a lot of pounding and it has always been up to the task.
I've noticed that in porns with uncut black people, you never see the foreskin go beyond the head. The glans never seems to be fully exposed. At least I have never seen it. Also, that red area under the foreskin is super sensitive and hurts even to touch.
So yeah, I was just wondering if there is any difference among the penis anatomies depending upon race (excepting size). I am black by the way.
