Is there any way to become asexual?

(Before you ask, yes, I am trans)
I have a very high sex drive. Sometimes I will just see a pretty girl and get horny. I don’t want to. I don’t like having sexual attraction, because it only causes me pain, because nobody wants to have sex with me, so the only feelings my sexual attraction gives me is anger, jealousy, sadness and lust.
I don’t want to have sexual attraction at all any more. Or at least much less. It gets in the way of my daily life and hurts me. Is there any way to rid myself of sexuality? Or at least decrease my sex drive dramatically?
