Just a Fantasy

So Im here at your "forum message board".
And I can tell I am kinda obsessed about it too, or at least girl-on-girl sex. Im having fantasies about it always and do nearly never fantasies about male-female sex, or well ofcourse I do...sometimes.
I dont know why, but I just find girl on girl sex more sexier than, imagin a man and a woman having sex, maybe I should blame the porn industry...(?).
Eventhough I am self very genuine with sex, can be sensual and dominant at the same time, and in fact when I do think about it, its mostly sensual sex that falls in my taste.
Allthought I prefer variation and being flexible with it, experiment with things, I am a sexual person I guess.

The top number one fantasy is that a girl I am having a relationship with and myself are having a threesome together with a another girl, and that she goes into a sex-battle against her while Im watching. Fighting out, tit-to-tit, butt-to-butt, wrestling, grinding and humping.
Then here's the point, (my problem), I would never ever experience this in real life, because Im way too much afraid and scared about it, just imagin my girlfriend being together with a another woman "for real".
There's some huge paranoia over it, maybe mixed with some homofobic influences, its too bad because I do always think and fantasise about it happen. Maybe its because Im afraid that the girl I love would turn bisexual or something and that my relation with her wouldnt remain as it was before...as pure as before.

Ive told this before on some other forum about the threesome thing, and everyone thinks Im really weird and paranoid ("supposed to be every mans dream you know...")

But I understand the moderators message, to be frankly, the thought of how it would be to being a lesbian or a woman have runned through my mind too. *haha*
Though Im very very comfortable with myself and my sexuality as male, eventhough this "fantasy" I have makes me confused and kinda turns to a issue when imagining it becoming reality.
