What does he do? A few months ago, I had a round of these conversations with the usual suspects in my life.
The Man With the World's Biggest Penis Can't Work Or Have Sex and Doesn't Care
Think of it as a dick Overton window: Boyfriend dicks have a measurable component, of course, but not a consistent one. Vaginas vary in depth and sensitivity just like penises vary in length and shape, and where some women may enjoy the mix of pleasure and pain she gets when someone hung repeatedly bashes into her cervix, others want nothing to do with it. For the first group of women, a inch monster looks like a Christmas gift wrapped up in a pair of boxer-briefs. What really makes a boyfriend dick is a holistic evaluation of the situation at hand.
But as much as American sexual norms have evolved over the past several decades, one stubborn idea remains relatively unchanged: When it comes to dicks, bigger is better. The accepted wisdom states that average penises are fine but big penises are greatly preferable.
