1. Has anyone done it before?
Yes, I have. I had over some 2-3 years gradually worked myself up to it.Imagining it, wanting to be in the role etc. I had practiced a lot with a prosthetic phallus and I had gotten to knwo a guy over almost two years via a website. Then one day it just boiled over in me. I wanted to, so I said to myself, do it, find it out. I contacted him, he was immedeatly interested, we met the same evening near a highway restaurant. He was really nice, but I felt that all his compliments and tenderness were towards another perseon - maybe not me - I just wanted none of the flirting, I wanted to get to it: Seduce him, perform orally etc.
That is what we did. I seduced him as best i could with my behind on his front, then kneeling, opening it up and putting the raincoat on as I had imagined it to do. That part went well and as planned. He was very enthusiastic about my performance I felt not a little flattered.
Then the first disillusion: I couln't do in reality what I had done to my prothetic piece at home. My throat wouldn't allow it. i tried and re-tried. No go. So I couldn't do what I imagined. What then? I tried to do what I could but after 5 minutes os so I felt sore and thouroughly unenthusiastic about it. It was like work. I kept up the smiles and the banter, but it was really work.
Felt even stronger that i was pretending to be something rather than being something.
This led me to renounce this route. That said the fantasy is still with me and still gets me excited. But I know it didn't do anything for me there and then. Sometimes I think I should try again with a different mind set but then again i feel that it in't what I am however exciting the fantasy may be.

2. Did you feel guilty later about it? - Yes.Not morally but towards him for pretending, towards his girlfriend (I learned there and then that he had one who didn't like oral). I felt really guilty about making him cheat. Especially because it was just an experiment for me.

3. Did you get addicted to being with a guy? -not at all. The fantasy is still there and maybe that counts, but definitely no.

4. Did you decide to go fulltime after being with a guy? not at all

Most Importantly
5. Was it more pleasurable than straight sex? How did you feel? - I have had good and bad straight sex, but this wasn't the right thing for me. So it wasn't.
