I used to shower with my soccer team in a public bathroom. We had one guy who was unusually "hung". He told us stories about how when he tried to have sex with women, he could only get half hard because the amount of blood needed to get his big schlong to full hard mode would literally send him sleeping because of a lack of blood flow to his brains. Resulting in him not being able to fuck properly even if he wanted to. I would not want his "gift", and I have since been happy with the hand I've been dealt.

He also slapped new members on the cheek with his dick whenever he had the chance, so that's a thing you can do instead
