Not much at all. I'm not the most sociable person, I don't need a lot of social contact all the time, but among friends, nothing's really changed. I think it would be very strange if I began acting differently toward all my friends due to their or my gender, like I was putting on an act. Although I have basically treated all people as the same/equal in my friendships, male or female, and I don't intend to change that.
But since I started the journey, I do feel less like socialising. I feel as though I might be more ready to do it when I'm done, but that is some time off. Maybe it's just that I still feel like I'm in pre-life mode, and when I'm done I'll be in life mode and able to go out and do things without constant discomfort or awkwardness. Maybe I'll be more social then.
