Bitch, please.
First of all, gay men are no more "sex obsessed" than their straight counterparts. The difference is, in our relationships, you have two male sex drives in play. So, while I never really like to generalize, let's put things in perspective, shall we? In a stereotypical straight relationship between a man and a woman, it's usually the man that is "ready to go" at a moment's notice. Sure, there are exceptions out there, but by and large, it's a widely-accepted "inside joke" in our culture that men will drop whatever they're doing, to have sex. So is it really a big surprise that when you put TWO men together in a homosexual relationship, there's going to be HEIGHTENED libido? After all, if your partner wants it just as much as you do, and you don't have to "beg" for it, etc... don't you think most STRAIGHT men would jump at the chance? I wonder if we polled most college fraternities, what those 'red-blooded American males' would say.
As for the "STD epidemic" in the gay community... firstly, let's not pretend that STDs are a gay-only phenomenon. But if, as I assert above, gays are potentially having sex more often (given MaleSexDrive x2), then the potential DOES exist for there to be a lot of guys out there spreading disease. Especially given that gays (especially younger gays) typically have more partners than their married, "settled down" counterparts. (Well, at least, the counterparts that aren't having affairs.) And, yes, I'll be the first to agree that men (regardless of sexuality) are typically riskier than women, when it comes to sex. So again, you put two men in a sexual encounter, you ratchet up the chance that they'll "throw caution to the wind". I'm not saying it's right, I'm saying it doesn't really surprise me.
Speaking for myself, I can tell you that as a child of the 80s, and having AIDS education spoonfed to me throughout my childhood, I was (and in some ways, still am) scared as shit to do some things sexually. Don't get me wrong... I love to fuck as much as the next guy, but A) it's not worth dying for, and B) it's not worth harming my reproductive system. Thankfully, my caution has paid off: I've never had ANY kind of STD, whatsoever. No crabs, no herpes, no syphillus, no HIV, nothing. But you know what? Having sex is, in many ways, a crap shoot. No matter HOW careful you are, you're always taking SOME kind of risk.
As for your comment about gay communities being a disgrace... I can only say that in my opinion, you're overgeneralizing. The "gay scene" in a lot of metropolitan cities can be quite a shock to the uninitiated, to be sure... but there are also members of gay communities out there doing great things for themselves, and for others. But again, I'll use my college frat party analogy... why is it OK for THOSE guys to behave that way, and not gay guys? Because a lot of the gay guys out in the gay bars are older than fratboys? Well, I guess when you've been forced to live in the closet for years, and you're finally able to be your own person, you go through a "kid in a candystore" phase. Maybe if it were more socially acceptable for gay relationships to be recognized, and gays could "settle down" like their straight counterparts, there'd be less fratboy behavior. Or, maybe not.
As for PuyoPiyo's original post... bless your heart, you poor thing. You have too many boys and men who want to have sex with you? It sounds like you're ready for something more than sex, and most of the men in your life aren't. I've got news for you, my dear: there are a LOT of women out there in the world, as well as OTHER gay men, who feel or have felt the same as you. That's why "dating" is a difficult field to navigate, sometimes. Finding that "special someone" out there who's looking for the same thing that you are can be daunting. Just don't give up. 
I do have a question, though, Puyo... some of these guys that you mention in your post... have they been successful in the past getting sex out of you, just by "coming over", "getting drunk", etc.? Where do you think their expectation comes from? Regardless, if you don't want these guys hanging around you just for sex, TELL them as much. If they have a problem with it, well, I guess they weren't really friends, now were they?
