I truly believe my history of childhood sexual abuse affected my sexuality. I am a male who is attracted to females, but I am also attracted to females who look just like females but aren't really females-- transexuals, trannies, ladyboys, BUT they have to have a convincing look like a female, and I am not bothered by the fact that they have a penis, as long as they have breasts, attractive female facial features, the penis on them and the fact it's like a real girl turns me on. I've seen a couple on porn sites and youtube, and I fantasize doing sexual acts with them whether it's me performing oral, or they on me, or anal-- but me doing them, while they masturbate and ejaculate. I can't be considered gay since I like females, so it must be bisexual but I'm not attracted to guys.
Pre-op transexuals are the best of both worlds if you don't like to think of yourself as being gay. The only problem is the hormones they take to look female will eventually cause the penis to stop working (arousal and orgasm). There are quite a few ladyboys that stay pre-op till their cocks stop working. Maybe you just like them and it has nothing at all to do with CSA? Whatever makes you happy is where you should go.
