The first girl I ever had sex with let it slip that I am small and by far the smallest she had ever had. My wife has also told me that I am very small. I have learned to love the humiliation, and it works well with me being a crossdresser. However I do feel bad for my wife as I have issues with staying hard and cumming to fast. I do my best to please her in other ways, but I really think she needs a bull.
Well, one girlfriend said I was smaller than her last, but he was 8 inches, so there's no shame in that. I don't think I've ever been called "small," though.
