18 yo male, need advice on my sexuality PLEASE

[Cuddly]

I started wondering if I was gay when I realised that I picked my porn based on the guys. I much prefered porns (still talking straight porn) with bulkier hairier guys and preferably more of them, per woman.
I was about 14 at the time.

I don't think getting erect at the sight of an erection makes you gay, at all. The erection is just a symbol of what's to come. Whatever the case, be true to yourself - these things are out of your control anyway.

As others have already covered, many straight guys become aroused seeing or thinking about penises because it reminds them of sex, their own body, and their own sexual pleasure.

yeah. a guy seeing a penis stimulated knows how that feels like, so it's natural for him to get hard down there at such imagery. seeing that stimulates parts of your brain associated with memories of your own sexual arousal/experience, that's a pretty straightforward connection. it's the same when going to a room you've had sex in, being there and recalling that event. that can get a guy hard too.

homosexuality is not just finding penises sexually arousing. it's finding more or less the whole male form sexually arousing, it's wanting to be with men not just to get off; it's when you're talking to a guy and you're not even thinking about sex but he gets you there by doing nothing at all, just being; it's being attracted to men -- their bodies, mind, and character. all of him, not just his dick.

The answers you all have given me have really made my night (just got back on because I make music most of the time), Im comfortable for the most part now. I might need to get used to it if I ever do decide to watch m/f porn at whatever given time. I feel like sexuality is way more complex then society put's it out to be. Day by day I woul spend time touching myself, watching people have sex. basically I loved having an erection, that love for having one made other erections eventually give me an erection. I loved being stimulated, so seeing another person be stimulated makes me want to be stimulated, therefore making me erect at the sight of the erection, or thought of one. It's all because I loved being erect myself. I guess the only weird thing now is the fact that it isn't known widely that we can all be stimulated by each other under the right circumstances, society makes that out to feel more wrong than normal.

Sometimes I think I'll end up being autosexual because though I do want a girlfriend (been single for a year and a few months), I don't connect with the girls around at my school, they're all stuck up and don't have any kind of intellect, don't carry intriguing conversations. But I can't imagine going my whole life with no one, self pleasuring myself, that's not what I want, no matter how much I like it. Then again, I hae no idea how my future self think of that.
