I have a crush on a friend who says they are possibly asexual

So I met this person in one of my college classes. I’m (21F) and they are a (23M).

We only met a few months ago but we became really good friends pretty quickly. We talk on the phone for hours at a time multiple times and week, and we get along really well (common interests, similar sense of humor etc).

We’ve shared a lot with each other at this point, including the fact that he self identifies as asexual.

However he’s admitted multiple times that he’s not really sure if that’s the correct label for himself, and he sometimes feels attracted to women as well as masterbates/watches porn etc. Apparently when he has alcohol he’s experienced attraction to female friends and done some making out at parties. So he seems a bit unsure of his orientation.

There was also a point when completely unprompted he told me I was a catch because I had a killer personality and was attractive. (We weren’t discussing anything regarding dating so that comment was somewhat random. I could totally be reading into it too much, but that planted the seed that there was maybe some interest from him lol).

He’s also made some off handed comments like “I think it’s okay to kiss friends”. And saying thinks about celebrities being attractive or liking boobs.

We also make a lot of sexual jokes back and forth which could just be because of our shared raunchy sense of humor, but sometimes (maybe wishfully) I think there’s some underlying meaning to them.

I’ve grown to really like him, and I want to pursue something romantic but I’m worried maybe I’m just setting myself up to be disappointed. I also really don’t want to lose him as a friend, but I just keep wanting him more and more.

I haven’t had a crush like this in a long time, and I have no idea what to do.

Help :/
