dick length is irrelvant. the inner 2/3 of the vagina have little to no nerve endings so it doesnt really matter if you have a 10 inch dick cause they cant really feel it. all the nerve endings are in the first third of the opening of the vagina so if dudes who are born with micropenis (yes its medical condition) can satisfy their parterns. whats more important is the ability to use your fingers while pounding them since most girls cant achieve orgasim directly through penetration. so stop worrying about your size and start learning how to MULTI-TASK bitches!
