My girlfriend and I have been together for roughly six months now, and she's started dropping hints about having a threesome with another guy. Maybe i'm being a bit homophobic or something, but i'm honestly not too sure how I feel about it.

My girl has admittedly more, I guess... um, sexual prowess (?), than do I; I've never had a threesome before, man or woman -- hell, i've never done anything that involves anyone besides my then- girlfriend or lover. She keeps telling me "it'll be fun! Come on! Its just a fun game in the bedroom!" and "all my EX-BOYFRIENDS did it and they had fun, what's the problem?" Well bully for your ex boyfriends then.

What's my problem with it? I don't know, exactly. I mean, i've watched porno of tag teams or even gangbangs -- I mean sure, it can be hot. But not when it's my girlfriend getting boned. It makes me almost angry to think about some other dude porking my girl -- in any other situation that shit's liable to get your ass kicked.

So why not a compromise? Why don't we try to have a threesome with a girl first and then have a threesome with a guy? "well, why do YOU get to have all the fun?" I dont know, maybe because it bothers me that there's going to be another penis in/around you that isn't my penis? you wanna be explorative in the bedroom? Let's try anal. Why does it have to involve some other dude's dick?

She says i'm being a prude but i'm having a hard time acting okay with this. I want to make her happy, but she says "its for both of us, it'll be fun!" but i'm pretty in love with this chick and the idea of some other dude railing her almost makes me sick.

I don't know. I need some advice.
