Women can display their parts by choosing sexy dressing. But men usually its all about height and muscles that is visible. Unless you are a black man , and women presume you have a good endowment, I dont know any way a white man an let this info known. I have the same endowment as an average black man or even slightly better, but dont know how to ude this for my own advantage. Any ideeas?
