How big can a guys girth get before an average woman can no longer deepthroat their dick? Also does anyone know the average woman's mouth circumference? In some pornos I've watched some guys have too much girth and the woman performing oral can't get past the head of their dick. I'm assuming this is around 6 inches girth? Also just out of curiosity do you guys who are on the bigger side of Girth do you feel your partners teeth on your penis when receiving oral? In my experience I wouldn't say I'm big in terms of girth it measures 5.25" and I've never had a problem being deepthroated by both guys and girls. Thanks if you took the time to read through all of this lol.
