EXACTLY what Spexy said. The size of a woman's labia has absolutely nothing to do with your pleasure during sex. The size of a man's penis has almost EVERYTHING to do with a woman's pleasure during sex- that combined with his movements. You can have a huge dick and not get a woman off if you don't know the motion of the ocean. But bigger dicks does mean more pleasure. The size of a woman's labia has absolutely nothing, nada, zilch to do with how good sex feels for you.
For me, I don't give a fuck what your penis looks like. It can be pale, tan, two toned, speckled, black, circumcised, uncircumcised, veiny, smooth, it doesn't fucking matter. I don't care what it looks like, and neither do most women. If you are good at sex and are a decent size, then we're happy. I don't give a damn how big your balls are, I'm not going to make fun of you for how small or big they are, if they're lopsided, if you only have one, if you have 3. It makes no difference.
Men are visual creatures. You can be the fattest, nastiest, smelliest, most dirty, disgusting man on the face of the Earth and you will STILL act like Megan Fox isn't good enough for you, because her forehead is too big, or her feet are too thin, or her eyes are too small, or her hair is too dark, or her legs are too long. Fucking hypocritical. Women are visual, but it is not what drives us. We are emotional, logical, physical, psychological creatures. Touch is what drives us, be it physical touch or mentally touched.
