Greetings. I had a surprise introduction. I was about 12 or so and had never had any sex education. I was totally in the dark about it. My first erection came as a result of my brothers and I playing good guy and bad guy. We were pretending to be captured and tied up (big surprise...not). We happened to be in a large closet and my brother pointed to a dress and suggested I put it on. The connection to the erection was innocent but established. At a later date I wore the dress while alone and had another erection. Not understanding what was happening, I just went with the good feeling. One day I had a climax while in a skirt. I was confused and concerned, not knowing what that was. By the time I found out its real purpose I was rather hooked on the practice. So, the basis is the sexual comfort and pleasure I get from it. However, I am in no big rush to climax while cross dressed. It just feels too good to end it, as the climax usually takes away the immediate urge. cheers, all.
