Am i bisexual or gay? (i'm a male)

The following is pretty vulgar. I couldn't find a way to avoid it without sacrificing being so detailed with my explanation, which will help provide better answers.

This has been bothering me for quite a long time now. I have considered myself to be bisexual for a few months now. However now I'm questioning again mainly because of something I've seen. For the first time in a film I've seen a closeup of someone fingering a vagina (I've always avoided seeing any fucking and stuff like that in porn, only blowjobs, unless it's gay or chicks with dicks) and I felt so disgusted to the point that I thought I was going to vomit. I did see photos of nude women before but not closeups and I also realized that I was never turned on by their genitals, in fact it's the opposite. Lesbian action is also a huge turn off for me. And then I thought to myself, if just seeing one makes me get this type of reaction, what if I actually go down on a girl?

I have always preferred women, by a landslide. But when I think about it, it rarely goes to me wanting to be intimate with them. My fantasies are usually that my crushes were actually futas (chick with a dick). I also preferred dick by a landslide for a long part of my life too, I was just in denial until I realized I was bisexual. So basically, chicks with dicks seems to be my preference. But I'm worried about that since most of them eventually want to get rid of their dick and probably even hate the sight of it, and they don't want someone to embrace it.

Basically, I lust after men (or basically cock) but I would prefer to be romantically involved with a woman. I'm just not sure if I will ever be able to be intimate with one.

Of course, the best answer would be to just go and find out. Have a one night stand with a woman or find a friend with benefits. However that's out of the question right now because although I'm usually considered above average looking by other people, I do have an acne problem (which I am on medication for now) and really, what's the point of trying when you have acne, especially being in the low 20s.
