Well, you described how you feel about sexual acts, but you didn’t say a word about sexual attraction or the lack thereof, so I can’t say if gray-asexuality or any other sexuality fits you. 

However, it sounds like you’re at least a little sex-repulsed, and that’s okay. I think you should look into asexual terms and see what fits you, but this alone doesn’t give me anything to tell you. Try reading this. 

Acenon, I can't tell you whether or not you're asexual. That's something you need to decide for yourself. But only finding guys good looking does sound like you could be ace. I also want you to know that there's nothing wrong with being asexual or being scared of sex or sex repulsed. You don't have to do anything you're not comfortable with. There are a people who chose to identify as gray ace since even through the feel sexual attraction, they don't ever want to act on it. Take some time and look at labels you think might fit. Try them out. If you don't like asexual or gray asexual you don't have to use them.
