Why do guys get annoyed when their girlfriends have fun?

Ummm, Well I would think that depends on the type of person someone is. Like are they easily annoyed,gets jealous easily,doesn't like when they are not the full center of attention from ther mate. But if you have an easy going layed back sorta person, not much bothers them because they know in the end no matter how much you are having fun they will always be yours and going home with you at the end of the day..

i dono...girls never get annoyed but guys don like em partying n havin fun by emselves :S

I think so

I think that is just a man thing, men don't want to think you could actually have fun without them.

You forgot something when you`ve started this discussion: "As lovely and sweet a girl can be, there is at least one guy out there that`s sick of her" ... hope it answers your question...

I get annoyed when my b/f is around a whole bunch of women that I dont know or trust.

I think that goes both ways because sometimes when someone's having more fun than you, they can't deal with it.

interests of a boy and a girl r totally different... different people get annoyed for different things.... so they cant b compared in that aspect..

I was married for 22 years and once in a while I would go to a single friends house. I always got a hard time about it even though she was free to go out any time she wanted. It is equal.
