Yes, I most certainly am. You said you didn't want to turn a woman into a "piece of meat" by getting an erection to her, and felt guilty and that something was wrong.Are you seriously questioning what is wrong for a trans woman to feel odd about getting an erection and feels very uncomfortable when it occurs?
People have sex drives. There's no need to deny that or feel ashamed of it. Furthermore, even if men have been turning you on more lately, it's not like you're getting kicked out of a club for getting turned on by a girl too.
