So the average girls vagina is only 3.77 inches deep and the opening is only 1.4 inches in diameter. So don’t worry about your dick size unless you’ve got a micro penis or something.
You don’t need a monster long girthy cock to please a girl. It’s about how you use it.
Besides I know I wouldn’t want to get split open by some guys massive 8 inch dong anyways.
P.S. vaginas do stretch to accommodate what you put in there though so it’s not like you can’t have sex if your dick is longer than 3.77 inches lmao.
