There's an even number of people in the world. I, a hopeless romantic know that my better half is out there, and we're going to meet someday. I could honestly care less if it's a guy or a girl. I know that when I meet them, my heart will be theirs.
I've never done anything with a guy. There is only one guy I know personally that I would actually consider ever doing anything with, and I happen to know he's not interested.
I find gay porn attractive. I find men attractive. I find the fantasy about the whole experience.
However, I have fantasized about many-a-thing in life, and then encountered the real thing, be it roller coasters, technology, meeting heroes & idols of mine, and even relationships. When I find these things in person though, it often disappoints compared to the fantasy. I set my goals way too high I think, and it'll probably be my downfall, but I wouldn't trade the fantasy and dreams of a Mr. or Mrs. Perfect for the world.
Sorry for the long speech, but to put it simply. I hope gay sex lives up to the fantasy for me. I really, honestly, truly hope it does, but until then...fantasyland for me. I'll take either, should we have LOVE holding us together.

At that point, all the "little things" they do will be more important to me than sex in the end.
(End of rant-i'm too long-winded I think. So sorry yall)
