That's an important distinction to make... no one should join a legit sport, club or league (whatever you want to call it) with intentions that deviate from the purpose. You will fail, and you will be rediculed when they find out your true reasons.
Don't get me wrong, if you get involved in MMA because you actually enjoy martial arts and you want to be a fighter, and then on the side, you happen to be human and have your human urges too, then that's fine. But know how to seperate the two, and when/where it's appropriate to express the different facets of one's personality. (ItsMyLife, I'm not pointing to you, you actually seem like you've got it figured out, I'm just speaking generally.)
I was a wrestler in highschool, and I think soon, I may start up at an MMA gym near me. Occassionally, I get asked some pretty rediculous questions (at least I find them rediculous) and they're to the tune of "did you get hard when you were wrestling???" ... the answer is NO. Now, I'm just as gay as the next homosexual guy, but the truth of the matter is, when you're out on the mat to wrestle, taking down your opponent is the first and last thing that is in your head. There is no time for lusting or daydreaming because if you do, you'll be off your game, and you'll lose. Plain and simple. So please, for any of those who think they're going to join an MMA-related discipline for erotic reasons, look specifically for the "fantasy" based clubs, and not the real athletic leagues.
I felt compelled to write this post mostly because of my past experience with people and their misconceptions. It may not speak to everyone, but I know there are a fair number of people out there who don't have a clear idea of what being a gay athlete really is all about. It doesn't help the situation when people are alreadying calling sports like wrestling a "gay sport." It makes even the least homophobic guys upset (who participate in the sport) and it makes it harder for us homosexual guys who are in it for the win to actually be apart of these lifestyles. OK! Rant over. :-)
Oh yea, and I agree with you ItsMyLife... I think I'd do well with a guy who happens to be an MMA athlete aswell. :-) One of my biggest gripes is that, in a real fight (if, knock on wood, me and mine got into a fight) who'd be holding the ground? I'd prefer my boy and me to be equally protecting each other, but more often than not, I can't help but feel like I'd be the sole defender of our little "team" there. I don't want a guy I *have* to defend. I want a guy whom we can equally defend each other if ever necessary. That's just one little thing, of course, I'm not expecting to get into a fight any time soon, lol.
