This thread was a parody of curlings foolish musings but I have found that sex is infinitely improved if your partner offers some outstanding physical or mental characteristic. A woman can be sensational in bed by knowing what to say and how to act while looking quite regular. Others can be great with less effort.
I would suspect that less endowed men tend to compensate. Me........I just say "suck it bitch."
I have an average one and I know some guys who used to date my wife who are hung like mules and she married me. I don't think it matters to most women that much.
