I don't have any sensitivity in my dick.?

I'm a gay male and I've been with a few guys now. I really enjoy helping them, but almost never enjoy getting help myself.

Masturbation brings almost no pleasure until the very end. And it's usually a chore to get there.

I really don't feel their mouth at all. Except the time the guy was a heavy smoker and his tongue felt rough.

Sorry if that's too much information, just wanted to clarify. I don't really feel any pleasure down there when it seems like I should. I usually have to fake moans and throw my head back to seem like im enjoying it.

I really only get pleasure out of helping others get off.
