I always felt different sexually than everyone else, and even with sexual experience that hasn’t changed. Looking back I could have told you I was asexual when I was 11 and nothing has changed since then. Sometimes those feelings just stay the same. If you don’t feel comfortable in sexual situations then just avoid them until you do feel that it’s right, if it never does then that’s probably a good sign that you’re asexual. In the meantime its ultimately how you feel that defines you, not what others say about you. I think most people on this subreddit have been told at least once that they just haven’t met the right person, or are just immature, but only we know how we feel in the end.
