A lot of it has to do with girth, and a lot of times larger penises are bigger around. If a guy has more girth than it feels better to the first 3 inches of my vagina, I guess. It is always awesome in a way if a guy has a large penis, but it's by no means necessary.
I've had sex with guys with penises from 5.5 in to 8 in., and the most pleasurable sex has just come from the guy I feel closest to.
Yeah that's true, but it's more about girth then length. It sort of creates pressure which is what causes the pleasure. And we're not the ones going on about penis length. No matter what we say about the motion rather than the size no one seems to believe it.
