People say I'm asexual but I'm not completely sure. I can get "in the mood" like any other person but actual intercourse is a no go. Help??

Do not let people pick your labels. It should be completely up to you to define yourself however you please. Someone who is asexual just feels no sexual attraction to people in general. You can be gay or straight or anything else and asexual at the same time. People who are asexual may or may not choose to have intercourse whether it's for wanting to please a partner or wanting to have kids the natural way. Some may enjoy it and some may not, it really depends on the person. There is an asexual spectrum and you can be romantically attracted to people while not being sexually attracted, and that's okay too.
