It's not uncommon. Since starting T I've noticed my sexuality might be slightly more fluid than I thought. To be with a guy pre-transition, there's so many reminders that our bodies are different and that I'm the girl. It's easier with a girl. Keep my clothes on, focus on her. I see myself ending up in a straight relationship long term, but I don't know where my head will be after top surgery when I'll feel comfortable getting more naked. I still feel fully confident about my attraction to women, the way they make me feel.. no words can explain. But I've been very comfortable exploring my sexuality (I'll just say it.. I'm talkin bout porn). So yea, it's definitely confusing, but it doesn't have to mess with your head if you don't let it.
