So I've already come out as gay to everyone except my brother, and the thing is, I'm sure I'm attracted to men, like 100%. There's no doubt about that. I can grow feelings for men, get butterflies, I get a "third leg" quite easily, etc. But the thing is, I can only stand very very soft porn, aka there needs to be clothing (shirtless is fine), no speedos. I do have a wrestling fetish, that can get me very hard very fast. But I've tried watching regular gay porn, with the penetration and all, but seeing the dicks and all make me flaccid, I can't even get to the part where there's penetration. I've only made out with some girls and one guy, nothing else. So am I asexual or just sexually immature? I'm scared. Maybe sex will be viable with someone I really love (and that I'm really attracted to), but I'm not sure :/
You don't sound asexual from what you describe, seeing as you're having erections toward men and possibly desire. It sounds more like you don't like gay porn. Nothing odd about that. Porn preferences don't dictate sexuality. I know that a lot of lesbians hate lesbian porn (I guess for the reason that it looks fake) so there could be a psychological reason you dislike gay porn but not men.
What you describe bears no similarity to asexual behavior. You don't say how old you are but I think it's far more likely that you simply aren't ready for, or comfortable with, thinking about sexual behavior with men yet. Nothing abnormal or unusual about that. As a side note, this is where I feel like the abundance of gross misinformation about what asexuality actually is and means is doing an enormous disservice to people trying to figure themselves out. Hopefully this fad will eventually fade away.
You definitely aren't asexual. I had a pretty similar experience when I completely came out to myself. Sex itself and down below seems extremely gross at first. You just have to get used to the idea of seeing people of the same sex naked, and any interaction. The first time I watched girlXgirl porn(it was not actual lesbians of course), I was extremely grossed out and intimidated by the thought of doing anything close to that with another girl. But things change as you become more used to the idea of sex and everything like that.
