I feel certain that I have replied to a similar thread to this so I am only going to give the “short story” version. I only used it to purposely make one person jealous, and that was a friend who went on about “breaking women in half” with his dick and had poked fun of me on a fairly regular basis for having what he had (mistakenly) thought was a smaller cock. I was changing with my back turned to him to go swimming and he made a comment along the lines of my being embarrassed about my size. I just smiled and turned around. He looked at it, got embarrassed, said “wow” and shut up for that day. After that he decided to tell me that it is “too big” and he certainly wouldn’t want it. He is one of the people who think that what they have is perfect.
