This got me weirdly thinking about what would be the perfect size and whether they could genetically select for that, then I realized I was thinking way too much about a web comic and should just go see if there is a porn version of Gattaca.
Penis size is specifically mentioned in Gattaca by the character supervising the urine sample, so I'm pretty sure they're already engineering that in the world of the story
Thank you for sayjng that. It just something that need to be repeated over and over again for those men who think they are somehow locked out of enjoying sex because of it
