avg size is 5-6 inches from what I read on "scientific studies & polls", of course those were dudes measuring themselves.

Not saying I am <4 or <5, but the gee spot is like 3" in or something? THere is another spot I forget them name of... the E spot of something, which has the same characteristics as the G... so guys with 3-4 inches will do fine, especially if they're with a smaller lady.
