I have a step-aunt who went through csa. She said she choose to be a lesbian. Now I don't know if she then was bi all along?
I have a lot of issues with men, but I have very close relationships with women. I always wonder if it would be easier for me if I was a lesbian or at least bi. But I have no sexual attraction to women... so that's just the way it is at least for me.
You can be whatever sexual orientation you are or want to be. You can have an excuse or it's just the way you are. You don't have to defend such topics to anyone... So long as you're healthy, happy, not hurting anyone, and not doing anything illegal: just be yourself
