Don't worry, same shit happens with me. The condom is a necessary evil, and yeah it's no where near as good as bareback. Have you had a long relationship with unprotected sex? If so, that's probably one of the reasons.

Another could just be the fact that you need to get comfortable with the idea. I remember with my exes it took a while to get to that point, probably like 15 times each at the beginning of the relationship where I couldn't come.

So more details bro!
