I'm struggling with my sexuality

Hi I'm 20 years old and I think I'm straight, but I struggle to find someone to be attracted to. The guys who I've made out with and was really attracted to are very few compared to the total of guys I've made out with. I've kissed a girl at a party once, but I don't think I enjoyed it that much. I still wonder if it was because of her specifically or because she is just a girl. Most boys I'm attracted to at first sight I feel as though they are out of my league, so I don't really try anything because I get shy. Anyway I just want a way to know for sure. I know I'm not asexual, I might be demisexual, but I'm a bit scared I might be bisexual. What's a good way to find out ? Without asking strangers to have sex with me please, that makes me uncomfortable 😅
