I recently became sexually active with an uncircumcised, really great guy... We have tried having sex a couple times now and its not working so well. I have read up on uncircumcised men and sex but I still have some questions. First, condoms are super hard to put on- is this common for uncircumcised men? Second, (while trying other birth control methods, because condoms didn't seem to work so well) while trying to get it in... couldn't get it ALL the way in - is this normal?Third is the foreskin supposed to come all the way back? He seemed fully erect, although there was still a lot of skin... I know I should talk more to my partner, but I wanted some outside advice and info before bringing up all my questions...

Unless he is inexperienced, I would discuss it with him. But be careful. Guys can be sensitive on the subject. I would emphasize, your inexperience to start the subject.

If you really like the guy, just remember, practice makes perfect.

Its not good to have a sexual activity with a 'uncircumcised' man because the possibility of getting sexual diseases are much likely to elevate. I think you and your partner should discuss these private issues.
Thanks and more power
