Coming out to people is a very personal thing and seems to be dictated by both the relationship you have with your family - if any, and when the urge to move on strikes you. I went FT very quickly but I didn't much care what anyone thought. To be honest it has been a non-event. I gave a lecture to 300 medical students two days after going full time, I had given a previous lecture the week before as a guy.
I got one personal question at the end of the lecture when a girl came up and asked where I had bought my boots!
