The honest to god truth? Size doesn't matter. I know that it may be hard to believe coming from a straight man that has no experience with penises like a woman has.
But let me explain myself a little. Is a guy with an 8" penis more likely to get married than a guy with an average sized penis? Do the guys with the 8" penis fall in love? Do women fall in love with them, or their penis? So far, it doesn't matter.
Now, in all actuality, we're talking about sex. A smaller womans vagina is not made to fit 8". In fact, it's probably too big. And a woman who says that she likes it, probably also has a fetish for pain than. The average vagina is surprisingly made to fit (and will be pleased better if they go with) the average.
My girlfriend has told me repeadetly that my size is perfect. Any smaller it wouldn't be big enough. Any bigger it would be too much. I can actually believe her on this. She's a slightly shorter woman (5'4"
, and my size is probably 6". (maybe a little under even).
Now, when you please a woman orally... it's about the way you move. The same goes with intercourse.
