I only read a few posts here, but, just gotta say my piece:
Some people here are way way way overly obsessed with labels. If you have a hard time labeling something, maybe instead of shoving the square into the triangle, reconsider that the whole thing is a bit stupid.
I'm a straight dude. I've never fucked nor in any real conscious way ever wanted to fuck/be fucked by a man. The idea of a masculine person like myself hugging me sexually, kissing me, it's definitely not attractive or hot to me.
However, I have fucked a transwoman. Yeah, she has a cock. Yeah, it's bigger than mine. (Not a joke). Yeah, I have sucked that cock, jerked it off, gagged on it. I'd probably even swallow her jizz if it came (heh) to that, but if you have experience with transwomen you already know the hormones can cause erectile issues. It's hard to cum, basically.
If she had body hair like me, facial hair like me, a flat chest, and overall "hard" body as opposed to her soft feminine body, yeah, I wouldn't be attracted to her or fuck her.
There's a lot of people, and I can only assume it's like 99% dudes let's be honest, obsessed with cocks. I could insert a childish remark on THAT observation, but, I won't. I'll just say... who cares? Are you attracted to people's genitals? I'm not. Probably some people are based on porn that basically is LARPing as a gynecologist, but I venture to guess most people are attracted to a person's face, body, eyes, smell, their personality, and whether they have a pole or a hole in the reproductive section is sort of irrelevant until you get right down to the sex act. At which point, if you're a straight dude, well, good news, trans girls have assholes and mouths. And as a dude who has personally fucked multiple pussies, mouths and just one asshole, the transgirl's, well, they're all basically the same in the end. It's a warm hole, it feels good, you bust a nut eventually. So, again, over emphasis on absence or presence of a vagina is, just being purely honest here and I hope it hits a couple younger guys and makes them think, it's just childish, it's silly, and it's a non-issue.
The obsession with "am I gay?!" comes from built-in homophobia that's prevalent in every western society, and I'm sure around the world. It's been historically demonized and people have had all kinds of shit from being called weird or ostracized up to and including murdering them. But you can ask yourself a pretty simple question: why do you care? Why do you want to label yourself and others gay, straight, bi, whatever? Maybe the entire thing..... doesn't matter? Why the obsession from some people on telling straight guys who fuck transgirls that they're gay? You know how that reads as, right? That you're not confident in your own perceived sexuality and you feel forced to shove others into boxes with labels so you can continue to think in your mind "ha! I'm not that one!" But why do you care? It's just fucking weird.
Caring about this stuff beyond a quick and easy throwaway for the purposes of finding sexual partners and porn is incredibly fucking weird. And no, this isn't me saying being proud of LGBTQ sexuality and/or gender non conformity "is weird." Clearly, as I've laid out here, I don't conform to many people's norms. I actually forget these ideas even exist because they seem so backwards and odd to pretend that it matters, and then I see comments from, and I'm really holding back on straight up insults, what I assume are very very young men, and I'm just like... *sigh.* It only hurts you to have weird, closed-minded outlooks on the world. Well, unless you act out on those weird outlooks. I'd really rather you just say "I don't personally want to fuck women with cocks." That absolutely fine. No one cares. Just cut with the antiquated, poorly designed boxes and labels. No one cares about that either and you just sound like an old man yelling at people to get off his lawn.
