Did my best friend's boyfriend have a right to get mad over this reason?

When me (I'm a male) and my best friend (who's a woman) were living in a apartment together, we would always change our clothes in front of each other, and thus we would see each other naked all the time. We didn't see each other as anything sexual at all, and so that's why we were so comfortable being naked around each other.

But when my best friend got a boyfriend, that all changed. He didn't like the fact we were getting naked and changing clothes in front of each other, so he asked her to stop (which she did). It makes me mad that he got so mad over me and his girlfriend changing clothes and being naked around each other, since he should've known by now that my and his girlfriend's relationship was completely platonic.

My best friend eventually moved out my apartment and into her boyfriend's apartment. But it still makes me mad that her boyfriend got so mad over what me and his girlfriend were doing, since it wasn't really that big of a deal.

I think the boyfriend is just very

insecure about himself and/or his relationship with his girlfriend, since there shouldn't have been a reason for him to get mad because of that.

it is completely normal for a boyfriend to expect his girlfriend only to expose her erogenously sensitive skin to him and in mandatory situations such as medical exams or same sex change up rooms. his girlfriend must be an exhibitionist to change in front of you. surely is not normal or acceptable behavior by a person with self respect. surprisingly this did not lead sexual activities with you. you were not sexually stimulated when naked with her? you don't show candy to a child and not expect him to eat it. she was trying to make it apparent she was available to you by doing such an unnatural act. I am sure her boyfriend will keep a close eye on her and you in the future.

Your best friend's boyfriend has every right to get mad. You're sure you don't have anything sexual with his girlfriend but he can't be so sure of that. So, in order to protect what he has, he has to act fast by stopping his girlfriend from getting naked in front of you.

It's natural for men to protect their girlfriend's from other guys. It's normal for him to act this way, so don't be angry with him. I'm very sure you will act the same way if you were in his shoes.
