i have a really sore/sensitive head on my penis?

I had the same problem and here's what I did.

I pulled my foreskin all the way back to completely expose the head. Then I cleaned it and the shaft using rubbing alcohol to get rid of any stickiness. Now that my fingers were able touch it without sticking, I gently moved them over the entire surface and around the rim as much as I could stand to do. It doesn't have to be painful because YOU control the pressure and how much you do it. I did this at least once a day but as it became less sensitive it also became very erotic and led to masturbation so I wanted to do it more often. Eventually, I began dry rubbing my head to masturbate and I still masturbate that way because it feels so good.

You can use a piece of soft flannel when you first begin instead of sliding your bare fingers over it. It's kind of a warm and fuzzy, tickly, feeling. The alcohol feels cold at first, then it changes to warm and tingly. I still like to put some on now and then because it feels nice.

It's really nice to be able to touch your glans without any pain and to be able to rub it for pleasure.

There's nothing to be scared about, it just takes time to get it used to being touched and you need to do it often at first to get the results you want.
