<human>: Can you provide a brief overview of the text?

Using a throwaway for obvious reasons. I've been dating my boyfriend for over 2 years, and we haven't had sex yet. He has tried initiating it before but I said no, the furthest we've gone is making out and doing foreplay, but not even oral. I know he had sex with a previous girlfriend, And I've never had it. It makes me upset sometimes when I think of the fact that he's done it with another girl, and maybe that's part of the reason I'm hesitant about doing it? I don't know if I want to do it, but I fear that he'll get tired of waiting and might eventually break up with me over it. 

I'm worried that I could be asexual? I'm feel attraction towards him, but I don't really desire to have sex. And I'm afraid of doing it. What should I do? I don't know if it's fair to just make him go without it forever but I don't know if I'm ready. What do you think? What should I so?
