Wellll, basically guys think that if you're bigger you're better in bed. Girls tell them that "It's not the tool's size, but how you use it," but at the end of the day it's more or less a matter of masculine pride mixed with preferences in sexual partners. And I get the feeling society sort of builds this idea in their heads that if you're not a certain size you're too small.

[Weirdly, this wasn't uncomfortable at all. She was talking about jealousy after all.]

Humans can be ... really dumb like this.
