I was just wondering, when I have anal sex , with a guys penis up inside me, how far does it actually go when a guy enters me? been trying to find any pics but cant.. was just curious ..
arfff anatomically average anal canal length 4 cm average rectum length 10-12 cm if you reaaaaaalllly have a long boner and trying to 'penetrate' guy with average internal organs, then after 16 cm you probably hit a dead end because the rectum will bend around 90 degree and turn into sigmoid colon
