Dear Amber,
I took the first set of pills about an hour ago. No detectable physical changes as yet. But psychologically, practically as soon as the pills hit my stomach I stopped thinking of myself as "a woman who wants to be a man" and started thinking of myself as "a man (temporarily, thank God!) stuck in a female body." My breasts don't even feel like part of my body anymore, just something annoying stuck on for no particular reason. Hopefully they'll be gone soon!
One thing I was wondering about was what kind of sexuality male me would have. Judging by the naked girl pictures I've been scrolling through for the last half-hour, I'm not wondering any more. My sexuality is becoming a lot more direct, focused on attractive bodies as bodies and not "the kind of people they are" which feels tremendously freeing. (Are you going the opposite direction on the same road?)
Generally I find my thinking is becoming more direct generally, more focused on individual factors rather than relationships. I guess there are gains and losses, but I'm comfortable with who I am becoming. More than comfortable--for the first time in my life I feel happy about the future!
