Possibly Asexual

I think I might be asexual but I don’t want to be (no shame to those who are) because I want to feel that passion with someone. I feel like I’d be missing out a big part of my life. But it worries me because I don’t feel pressured to act sexually towards people in those situations and I don’t feel the need to masturbate either. Is it just because I might not be ready or because I might be asexual? Is there a way to reverse it?
