How old were you when you began questioning/considering you weren't "normal"?
I'm in my 30s and almost all at once feel like I'm not sure what I am in most demensions and struggling to figure out what I feel about anything. I've been married, happily for a while, which adds a little to the confusion.
I had my first homoerotic experiences at 18, realized I was bi and trans at 24, came out as bi at 32, as gay at 40, and trans at 42. In retrospect, I would have been much better off coming out (fully) earlier. Unfortunately, I was born into a conservative, patriarchical family and it took a long time to shed all of that awful self-loathing baggage.
