Curious...

My husband is uncircumcised and he's the only one like that, that I've been with. I keep seeing all these comments and posts that when you're uncircumcised, during sex then skin pulls back from the head and looks like a normal penis? When the skin pulls back on my husband, it's tender and he can't stand it. It hurts him. So when we have sex, he keeps the skin pulled over the head and has to be careful when he goes to pull it out, because if it touches anything while pulled back, it causes pain.
