Workings of the foreskin ?!

Workings of the foreskin ?

Ok cant seem to get an answer to this so i'm going to explain it thoroughly. On sum penises the foreskin will retract on its own but on others the foreskin will stay over the head during erection and can be pulled back manually to expose the head. As far as i know this is all normal. But when having sex, when you pull it back to insert it, wont it fall back down when its inside ?. Also wont the skin on the penis just move instead of the actual penis moving in and out the vagina ?

When you pull the foreskin back from the head and put the penis in the vagina, the head is exposed. Then, you pull the penis out of the vagina, and yes the foreskin will roll back over the head. Push it back in, and it will slide off the head again. that's kind of the point of the foreskin, to create added pleasurable friction on the glands of the head of the penis. And when the penis is not sexually active, the foreskin acts as a barrier to protect the sensitive head from rough fabrics, dirt, and other irritants. Guys who have no foreskins are less sensitive in the head of their penis because it is unprotected. Many guys who have a forskin find that it hurts to directly touch the head of their penis with anything but a vagina, because it is sensitive, and must use the foreskin by pulling it, and rubbing it on the head of their penis to masturbate. Secondly, no, the skin will not be the only thing moving in and out because think about it, their is a whole man attached to the penis, pushing, and pulling it in and out of the vagina, so the penis brings it's skin with it when it moves. I tried to be as clear as possible. Hope it answers everything you needed to know.
