Interesting thread; and I pretty much feel the same way as FA. I very much enjoyed my years of being able to just pick any guy I wanted and go for it.
My childhood was crappy, I couldn't have transitioned then even if I wanted to. My life was purely focused on survival
Early teens, school...eugh no, I can't think of anything worse than transitioning during secondary school. I got my ass beat on a daily basis just for being a goth.
Late teens when I moved out on my own was when I started to question my identity - it was also the first time I had the chance to explore the world around me properly and experience things. I had a lot of fun being young free and single. I still carried on my lifestyle when I started to transition but it was a lot harder and involved way more effort than just going to a club and picking a target.
Then of course I got pregnant

which would have been way less likely to happen if I had been an early transitioner, that lead to me moving and meeting the guy I'm with now...I couldn't picture my life without him at this point.
I've made up for my lost male youth by going back to college, so I'm getting the socilisation and getting to act like a teenager again. Then I come home and I'm a grown up with a family. The only thing missing from my "male experience" is the dating....which I am actually REALLY glad I don't have to worry about. It's probably also helping my studies because knowing past me I would have slept with half the student body by now given half the chance xD My class is 100% straight dudes....I've pondered how it would have turned out if I had gone into this class as the only girl.
I've never given much weight to things like destiny and "everything happens for a reason" but the way my life played out to get me to this point seems pretty perfect

wouldn't give up the journey or the destination for anything
