If I have a boyfriend, is it wrong to have guy friends?

No it's not wrong! He can't expect you to not have contact with the opposite sex because your dating him. I'm in the same boat as most of my friends are guys, I'm more of a tomboy. None of my boyfriends have had an issue. My current boyfriend has many friends that are girls, and I don't have a problem with it.

Some situations may not be cool with the opposite sex, even if you are just friends. Changing in front of them, sleeping in the same bed, an other "intimate" situations I think shouldn't be done with opposite sex friends when one is in a relationship.

No it's not if your "boyfriend" tells you otherwise then you need to dump him because he is just that a BOY but not a friend. You need to be respected and trusted, not controlled. I bet he thinks he can have "female friends" on the other hand.

Not at all. If you had a history with any of these 'friends', then I could maybe see your boyfriend's point. As it stands, he is being insecure and controlling.

It's not wrong at all. If he doesn't trust you around your guy friends you've had for a while that is his problem he needs to sort.

I don't see anything wrong with having guy friends but if we are in a relationship, and are spending time with "guy friends" i think it's a good idea our boyfriend is included. However, i have no desire to spend time with other men, except the one i'm seeing. Why? Because i'm interested in him, NOT them.
