Ah, this question never ends. Does size matter? In a way, a bigger penis might make a man more self-confident—which as we have discussed, affects sex drive. And typically, when you are confident, you are also comfortable, thus will be able to perform better.
Fact: The thing is, confidence does not come from the size of one's penis alone. A man with a smaller member may know how to work it better, just like how a well-endowed man who does not know what to do with his gift can be at the losing end.
It's just like how some men are not necessarily attracted to large breasts or big booties!
