In my experience most guys have a thing for their own man tool. They enjoy showing it off. They enjoy using it and getting off with it. Some such as yourself embrace the size of their penis as a way to display it and call attention to it either for it being much smaller than most or in other cases because it is much larger than most (John Holmes comes to mind).
So no I would say you are very normal and like most other men. However unlike most other men you prefer to use your dick for humiliation but still it calls attention to it and brings you some level of excitement and pleasure. I know some women really get off on humiliating men with small cocks so you would be bringing them pleasure and entertainment. So there is a special little nitch you have found for yourself and it works for you. Excellent I'm happy for you. Instead of worrying about the size of your cock, like most men seem to do, you have embraced it and made it not only work for you but it brings you pleasure. I wish every guy could learn to embrace what size they were born with.
Most women really aren't interested in the size of a man's penis but the size of his greatest sex organ, his brain and knowing how to use both to bring them both the greatest pleasure. A woman wants your heart and loyalty. She wants you to be there for her. So to all men reading this please forget penis envy and embrace what you have. I for one love all cocks no matter how large or small no matter size shape girth length color or age. They all give in pleasure.
