Women, if a guy is crowding you, do you have any qualms about raising your knee sharply into his "jewels"?

i have to go with "nooo". i mean, it can be funny when seen in the movies, but it's super painful. and i don't think anyone who is just "crowding" me, deserves that kind of a pain. it's really cruel. plus, it could damage him for life. so, don't do that. :)
