I came out as trans 2/3 months ago and so far it's going okay, though my parents are still adjusting. Now when I first started this process I was pretty sure I was gay as I've always had a strong attraction to guys and only had boyfriends before. Then a few weeks ago out of nowhere I started getting fantasies about a girl I know. she is one of the only two girls I've ever had a crush on, but it was a long time ago and as far as I was aware I was moved on. The thing is we don't talk much other than when around other friends. Me and her have never had any deep conversations, everything I know about her past is via our best friend. Generally when I look at a girl I can tell they're pretty, but never feel any type of sexual attraction, except in this one case. It's really messing with my head cause I was so certain I was a gay guy. It was one of the ongoing thoughts when I was trying to work out if I was or wasn't trans. I'm not planning to do anything with it, she has a boyfriend and even if she didn't, I doubt she would be interested in a transman - especially one she knew for years as a girl. But since the fantasies started I've found it harder and harder to feel turned on when thinking about other guys. Could this mean I'm bi and just fluctuating? Or am I really straight and not gay?
I don't know why you'd jump from gay to straight on the basis of one experience... I have read that sometimes trans people feel their orientation change the longer they spend in their correct gender and I guess it would make sense for your brain to connect to someone you already knew. I wouldn't go rethinking your orientation just yet. How many times do we get people here asking "I thought about this one person, am I gay" and we tell them that they shouldn't assume just because they like one person!
Point xD I'm probably just Bi, it's just a total shock to have such sudden strong feelings when I've never looked at girls like that before :/
