I don't even know my size. Since all I use it for is urination and masturbation, size is somewhat irrelevant.
Most relevant and sensible post in this entire thread.
Also since the erogenous zones inside the vagina are 2 to 3 inches deep maximum (I bet many did not know this), anyone at least 3 inches of size can satisfy women the same as someone with a dick as big as a stadium. And most people are within 5 to 6 inches of size so a bit smaller or a bit bigger than that is irrelevant (except maybe to your immature egos).
