as you already now question on orientation is very complex and covered with many layers, don't push yourself, sometimes it looks like impossible to get some straight answer there. Please take it easy, it seems that you are in some vulnerable and shaky place.
My CSA didn't make my gay, but made me confused, and like imprinted, I guess same sex attraction would always be there in background. I never acted with men nor I would, I don't care for it in real life but in my fantasy world there many things are happening and that is confusion.
Hang on man, don't be hard on yourself, you are doing right steps in your healing. Some time is needed for things to settle. Share with us as much as possible, let all that out.
Take care of yourself.
