Demisexual. Separate emotions from sex?

So I am single for the first time in decades, and unfortunately I have a very high sex drive. I've been on dating apps but never really connected with anyone I felt I could actually sleep with, despite the offers lol. I had a bad experience with a FWB (long time friend, first time hookup - totally ghosted me after!) so now I have no idea how to go about this. I have trust issues and self esteem issues now because of my past relationship, and I wish I knew how to satisfy my libido without letting myself get hurt. I'm definitely not interested in a relationship for a long while. Any tips?
