I hate the labels, but for those who like to do that crap here's what it is.
There are lots of straight men out there, may be married or have a girlfriend, love girls, and only women, have no desire to be romantically involved with another man, nor want another man's penis in his mouth or in his rear ha. However their girl may not be into oral sex at all, there are girls who do not, and will not do that, because they think its totally gross, and if you're hairy down there forget it!
So these guys will maybe pop online or whatever and meet a guy just for the guy to go down on him and that's it, everyone says guys do it better down there than women, and girls seem to think other chicks do a better job down there than a man, so he'll have the guy do the tootsie pop on him, nut and then bounce.
Then we have our guys who love being worshiped. They're all very into themselves, think of themselves as gods ect, they'll go around talking about how much pussy they had blah blah blah, but in reality MOST women are completely turned off by this kind of behavior, and the thing that turns these men on has little to do with sexual preference, they get turned on by praise and adulation. Gay men are more willing to cater to that guy's ego, so he's going to have a gay dude feel on his muscles, talk about how great he looks, blah blah blah, he'll let the guy blow him, and then he'll be off.
Then there are the vikings as they're called in my sport. These guys totally get off on abusing, dominating, and humiliating people. In the old days guys like this would go about snatching up girls doing violent sexual stuff to em and then move on. The same is still done today, but because we live in a more civilized society, where these type of guys don't hold the same kind of power or fear among people, they'll go to prison if they do this, and he can kiss his fighting career bye bye, so what's a guy like this to do? Well he's going to snatch up another man, but not just any guy, and certainly no man who has some freaky fantasy/fetish of being dominated by another man, he doesn't want that, he's going to go after a man who is masculine, and basically wouldn't want that, because again domination, and humiliation is what turns these guys on, and the real deal at that. And another man especially if the guy is all masculine is most likely going to be WAY too ashamed, and embarrassed to let anyone know he got raped by another man, so then he basically gets away with it, and it makes him feel all powerful.
In prison guys will do this of course, because its the worst thing you can do to another man, treat him like he's a "bitch" less of a man, making yourself, and the guy you're dominating feel like you're the alpha male, they view it as turning other men into women, and that's funny to them.
(I know 2 guys who've had this happen to them, and it messed them up, and one guy who does that to other guys, we obviously don't hang out)
Then we have guys who may engage in sexual acts with other men, because there is no pussy around, some men will just use their hand, but for some they just want to stick it in something so bad they'll just go on and plug another dude.
Then we have the kind of relationship which everyone today calls a "Bromance" where you have 2 straight men, who may love the hell out of their wives, or gf's and love pussy and all, they don't get turned on by other men, never thought about doing another man, and get all grossed out by the thought. but they have such a strong bond with each other, and love for each other that they could never have with their woman, and no other man who isn't like them. These guys aren't ashamed, or afraid to show normal, natural emotion between each other the way close male friends always used to do, until people started labeling people.
They'll cuddle with each other, play fight, kiss (not tongue down the throat kiss). haha there's even this dumb mini holiday on August 14, which is 6 months after February 14 (valentine's day) called "Bromance day" where you hang with your best bud and do all the bromosexual stuff with him. As far as sex goes there is no oral, and anal sex between the two, just the cuddling, and the light kissing, if things get that hot and heavy between them, and they're VERY close, the only thing they'll get into is the frot stuff (google it)
(this is the kind of relationship I have with my best friend since 2and grade, his girl, my girl, and everyone at the gym call us Bromeo, and Dudeliet haha)
Gay men just enjoy/want/love other men, and usually will feel the same emotions towards a man, that a woman would, and they want nothing but another man. Nothing wrong with that.
Bisexual men like pussy, but at the same time they may like dick in the mouth or in the bum as well, go for it if that's your thing haha
I never go by the whole straight gay bi labels crap, because every straight guy out there in the world, has at least 1 guy they'd get all into in a sexual way, doesn't mean they're gay, and it doesn't mean they're bi, can't call it anything.Some men just may be curious, and want to know what its like to suck a dick, boink, or get boinked by another man, they'll try it, may end up not liking it, or end up liking it. Just don't be messing with little kids or animals is what I say haha.
