I just... can’t.

So I recently got out of a two-year relationship with the guy I lost my virginity to. Before him, I don’t think I ever really masturbated and definitely never had an orgasm. I chalk it up to my inexperience and poor communication during sex, but he never made me cum. Even after I got more comfortable telling him what to do, I could get close but never there (alternatively, I can masturbate to orgasm pretty easily). I’m starting to move on to another partner and I’m scared that this weird mental block won’t go away. Any tips on how to let go?
