Confused... Need some things cleared up.

Hey guys, I'm confused and need some things cleared up for me.
I know that I am in fact gay, and I have known for quite a while now. I might also add that I'm perfectly fine with it.
There is one thing that has always been on my mind, though. So like I said, there is no doubt in my mind that I am attracted to men, however what really confuses me is that for some reason, watching lesbian porn also really turns me on...!? It's so weird because like I said, I like men. When in public, I check out the MEN around me, not the women. I don't believe I am attracted to women at all, and would not be interested in having sex with a woman. Actually, I don't think I'd even be able to get a hard-on if I were to even try to get with a girl. However, what I find weird about all this is that if I were given the chance to have sex with not one, but TWO women, I'd do them both in a heart beat. I'm beginning to think that I'm not actually gay in the sense that I find men attractive, but more-so in the sense that I just like the fact of two MEN being together. Butt-naked, making out, the whole deal. And I think that's what turns me on when watching lesbian porn too. Not the actual women themselves, but the single fact that they're both women, butt-naked, tits rubbing against eachother as they make out. ****, i'm beginning to get hard just thinking about it. I feel as though if I were born a woman, I'd end up being a lesbian because i would turn me on to be with another girl. I don't know what it is, theres just something about the idea that I find so ******* sexy. Like, it's viewed as "taboo" and "wrong" by society, but yet it's so damn hot. I'd also like to add on the side, something that confuses me even more, is that, even though like I said, I am 100% gay. I mean, I'm a pretty manly guy - very athletic, love sports, like working out, but I love men and everything manly. However, on some occasions, I like to watch videos of girls by themselves, talking dirty to the camera, fingering herself or whatever it may be. It does take me a bit longer to cum when watching these sorts of videos, but they get me there regardless, so I'm like what the ****, if I love men so much why am I turned on by this? And then I think, naturally, I must be bisexual, right? But what makes me skeptical about that is the fact that, for one, as mentioned above, when I'm out in public I ONLY check out men. Second, when I watch "straight" porn, M/F, it does absolutely nothing to me. Like I get bored... there is nothing sexy about a man and a woman having sex in my opinion. But then I think of those videos I watch of those girls going solo, rubbing their tits and fingering themselves, licking their lips, its like **** thats hot!!
Anyways, nobody is probably gonna even end up reading this post since it's so long, but if you actually took the time to read it, please by all means leave a comment. I'd like to hear what other people have to say about this, and if anyone is in the same situation, or a similar one (which I doubt, but who knows!). And if you have nothing good to say, then don't say anything at all. I am not remotely interested in reading comments that will do nothing but insult me.
Thanks,
Drew

EDIT: BTW, I had absolutely no idea where to post this question, so I decided to post it here. If you can recommend another site or something that will provide me with better answers, please do so, thanks.
