text: what is the size of an average penis and the depth of a vagina?   first of all - black men are not "larger" than any other men. it is a myth.  i know people who've had small black coc, and had asians who had big meat. so what!!  average size flacid is about 5 or 6 inches.  average size erect is near 9, but men all have different sizes when erect. some are tiny and then become huge when erect.  as for the vagina - women have different depth inside. less than 10 inches to reach her cervex.  not too many people care that much about this stuff.  if you can't fu*k, it really doesn't matter how much meat you're packing.
