I think this is really common, for people with trauma and difficult situations, as well as people in general. I think there is a lot of pressure out there for things to be a certain 'way', or to be 'normal'. With something so intimate and personal, who is to say what things should be like. I used to have issues but I feel I'm in a better place now, although still I struggle.
I would recommend thinking about what you want, what you really want from sex, and how that would work.
I also feel such energies are connected with creativity and other activities. Doing 'sex' in isolation just doesn't work. Do you have any creative hobbies or passions?
Good luck with it all. It's an ongoing and constantly shifting thing for us all :):hug:
