I generally fantasize about previous sexual partners or those with whom I would like to have sex. My first sexual experiences as a young teenager are favorites. Also, I had torrid affair many years ago with a really hot redhead. She was the best sexual partner I ever had and I remember almost every rendevous we ever had, although that was more than 30 years ago. I also think about particular teenagers I knew as a young man who were especially well endowed with whom I would like to have sex, but never did.
