I'm in the same boat as the OP! While my cock is pretty average according to statistics, I love it when SOs comment on it being smaller than average. I remember I had a girlfriend who told me as far as she was concerned I was smaller than average and whatever I read was just to make guys like me feel better! I thought that was hilarious and sexy it turned me on.

When she and I learned the affect it had for her to say comments like that it became a important component in our sex life!
I never took it as "humiliating," just fun, hot teasing! I hope I meet another girl who would enjoy it also. A big fantasy for me would be to be in a threesome with a well endowed guy and have the woman make comments comparing the sizes as part of what goes on... you can see videos where this scenario is staged and they always make it where the smaller guy is traumatized by the experience. I wouldn't be at all!
