I'm not on hormones and don't have any plans to get on them.
I do know someone who was on them, then decided to stop, then started again, then stopped...it was a back and forth thing. I tried to tell him that he/she (I knew this person both ways) needed to commit one way or the other and that stopping and starting just wasn't healthy. After deciding to totally quit hormones, he's now regretting it because he decided to give up dressing, and now when he takes his shirt off, he has semi-developed boobs. He's now kind of self-conscious about it and has some regrets...at least last that I heard.
