Sexuality??

I don’t really have anyone to ask, so please tell me what you think.I have recently come to the realization that I am disgusted by dicks, and it scares me. I come from a background where if you’re going to date someone, you are marrying them, so I can’t just experiment or anything. It’s like if I do the deed with that guy, then I’m stuck with that guy, so I’ve been reading stuff online and seeing the real deal, and I’ve concluded that it’s disgusting and it makes me feel nauseous, but I’m straight. I’m attracted to men, but like, the only part is the penis; it throws me off. I also don’t have trauma with it, so I’m just confused, and I’ve explored the idea of being asexual or a lesbian, but really nothing has made me feel like I was attracted towards women, so I’m definitely straight. I really have no one to ask this about.
