To answer this;
1- I have done it only twice on my whole life with a man while I was a girl. I have been a CD for 10 years.
2- I did feel guilty afterwards when I got back into boy mode. But while I was in girl mode, it was natural.
3- I am not addicted to it, but I guess I would not mind it in girl mode. It offers me a chance to loose myself in the fantasy. I want to be loved and desired as any woman would. I want to feel delicate, cherished and sexy at the same time. I want to feel powerless and let someone take control of me....perhaps use me.
4- Not going full time.
5- The feeling I got was really special. I cried the first time I did it. I remember very clearly the whole event as it was my first. It was a man older than me by about ten years. I had chatted with him online for a while and finally decided to meet. He was very gentlemanly. He in fact told me if I wanted to stop during the process then say the "safe word" - as he wanted to act out several fantasies of his.
He wanted told me to take a long bath poured me some wine and I got prepared for the night.
He watched me apply my make up and finally get dressed in a rather transparent nightgown I brought. He has some other items of lingerie for me to try on as well.
Then the "night" began.
I was the recipient of his "advances" and it was my first penetrative experience. I was really blown away. I screamed and cried at the same time. It was almost too much for me. At the end I was so tired all I could do was to lay there for a sleep. I did not "come" during the process (although it was so erotic and sensual) but the experience was so different it cannot be described or compared to the "regular activity".
