I never heard his reason for doing it.
He’s insecure and wanted to feel more “masculine” by overcompensating and literally increasing what he feels makes him a man: large muscles, oversized genitals, beard, tats, etc. Next question.
 
Oh my GOD I stumbled upon his naked pushups video and managed to find him, what the actual fuck did he do to his mother fuck ing genitals?
Idk if I’ve ever seen that one.
