Oh this is just bullshit. You know what you enjoy. If someone asks my sexual orientation, I'm not afraid to give them the full run down; I have nothing to hide. I tell them that I'm openly gay, and sexually bisexual. I just don't care to date women. And if any of you want to tell me that technically it's "bisexual, but leans more towards men", I could go with that, and there's nothing wrong with it. I'd like to see more men on this site say "bisexual but lean more towards women," if that was to be the case, but oh well to that.
If you can say that you've slept with another man, and you have no intentions of doing it again, but you can jack off with one, then news flash, boo boo. Not all gay men engage in intercourse, or care for oral sex; the same with heterosexual couples. What you enjoy sexually with someone is merely preference. And if you can jerk with and to another guy, then you still appreciate the male form, and it's still a homosexual act. And here's how you know if you're fooling yourself. Ask your heterosexual buddies outside of this site if they ever jerk off to or with other guys, and see what they say. Some of you wouldn't dare think about it because you already know the answer. And you could say "well, they just wouldn't understand." And maybe you're right? Maybe they're just more closed-minded, or maybe you're just more open-minded than you care to admit.
I really don't know why we keep posting the same thread with different names and different approaches to the same question. I mean, really the question that's being asked is "is there something wrong with...?" No! You are who you are, and you enjoy what you do- don't take shame in that. For fucks sake- I know it's a straight world, but lets change it. Instead it's like a shitload of nazi's who read and practice the teachings of the torah in private!
So to answer the question of the original poster, does straight curiousness exist? Absolutely! But once you cross that line, and you've explored that curiosity, you are no longer curious. Be a man and suck the dick, I mean, swallow it up. Fuck, I mean Suck it up!
