Hey guys, new to the forum. This may sound like a stupid question, I'm 18 and I'm having some problems with my foreskin. Although I can pull my skin back no problem when soft, I do have a little difficulty pulling it back when hard. I know there's a name for the condition - as I've read about it on the site. I can pull it back with very minimal pain, and have no problems with the actual foreskin. This is not my question, I'm just setting up my situation. My real problem is the head of my penis. When the head is exposed, it's very sensitive to touch, to the point that if it is not lubed up and I touch it with my finger and pull it off, it hurts. Also, in the shower if the water falls directly on the head, it hurts. I know it must be let out in the air for it to gain.. sort of a skin on the head, instead of having it like it is now. (see pic) As you can see, the head does not have much of a "coating" on it, like other penis heads do. My question is - if I let the foreskin slide back over my head, and allow my penis head to "air out" and gain that kind of overskin that other penises have on it, how long should I "air it out" for? Is there any risk to leaving the foreskin behind the head for hours on end, or before it rolls back over the head of my dick? Sorry for the wall of text, and thanks to your replies.
