Obviously, mi wife knows. It would be very hard to hide all the changes from her. But there is no need to, she is very sympathetic.
Other then her, my father knows, as I had to change my diaper once when I was at his place, and for obvious reasons I had to let him know. Although, he was concerned for me and my wellbeing, he was really understanding.
This weekend I told about to a close friend. He was really cool with it and was very sympathetic and understanding which was nice. And this helped me accepting the fact that most probably this is going to be my life from know on. The fact he was so cool with it, helped me accepting myself a lot.
