Bet you're going to get a bit of an unrepresentative sample here. The average erect adult male penis is something in the league of 5.5". If that were insufficient to women, the species wouldn't be very successful, would it? I like to think that, even among women who prefer larger endowments, love (or at least personality) is paramount.
That's not to say that people are not entitled to their preferences. We all have them. But most women will have no qualms with an average-sized guy, and even those who have preferences -- unless it's a one night stand -- will put you ahead of your penis. I would hope.
My two cents. :)
