Totally agree that there is definitely such a thing as too big. Size matters - to an extent. I am a firm believer in personality making all the difference. The most attractive guy with a decent size to him will be ugly as hell if he has a bad attitude or nasty personality. Just like a guy who may not be "hot" or have the biggest one in the world could be super sexy to you because he has an awesome personality.

Check this out. People of a certain level of attractiveness tend to flock towards those of the same level of attractiveness. This goes with friends too - not just significant others. There is scientific evidence of why certain things are attractive to people.

That is a good one too - from this website even! So of course there are extremes.....I don't think size is the end-all-be-all. Not to mention - some women can't achieve orgasm no matter what. And those that can, a lot of them can't reach it vaginally but have to be stimulated at their clitoris to orgasm. And even then there are so many other things that go into it - smell, visual, touch etc.... A guy with a large penis can be terrible in bed just like a guy with a small penis can be awesome in bed. Way too complex to make it such a black and white situation.
