my botfriend is uncircumcised too and at first he smelled bad and one night has I was getting ready to go down I told him I couldn't cause it stuck. He got up really fast and ran into the bathroom. He came back and had washed it off but it smelled like soap and kinda like a girl scent a little. In your case, it might not been another women but you never know. Did you ask him about it? If it is, he might of not clean it off very good. Or it might be the soap he's using.

Well that is a bit odd, are you quite sure that it was another woman's? i mean are you sure that it is not just because he maybe hasn't showered that day, because when i guy doesn't shower his member can get sweaty my bf has been like this b4 and i know he has never cheated on me.

If you are not sure or feeling paranoid you should confront him nicely and just explain why your asking him and try not to yell because you both will just argue good luck Jenny

An clean uncircumcised penis will usually have a scent that is very much like the scent of a vagina. This is normal and does not necessarily mean that he is cheating on you. If it is overpowering, Suggest that he wash.

It's called smegma.

i am a women and i never experience this with any of my boyfriends. i have experience my son's father private area smelled so bad i thought i was going to barff.
some guys arent very clean!
some guys are very clean like my current boyfriend. you could be wrong, but i would do everything to find out if it is true or not.
