I like Kato's comparison about the tata size. I did not mean to make it sound like anyone has been laughed at for anything, I made the comment in jest... I'm sure no one here (at least I'm hoping no one here) has been laughed at like this, cuz that would reek horribly.
The comparison though, in my opinion, says a great deal about the aesthetics of things. Us guys like the size of a big breastisis... but there comes a point when enough is enough, you know? Kato's right... there's so much more than penis size when it comes to it. I've gotten girls off using, literally, 1/3 of my 'arsenal'. The G spot is very easy to hit once you know where it's at, and it doesn't take 12 feet to get there. Realistically, al that's up there is cervical wall..... and ask any chick who's been bruised, or had a guy go a little too deep for a little too long on her... they'll tell ya it's kinda uncomfy. How do I know? Like I said, I don't like tootin my own horn, so just trust me.
It's a matter of preference, really,... a mentality, if you will. Some girls who aren't necessarily "high-mileage" may want a bigger guy, just to see what it's like. Some may know what they like. Some are happy with 3 inches. The sexual pallette is so diversified these days, it's more a game of finding your match than worrying about if there's a match out there.
