He kept one hand covering his crotch

He took off his clothes and went into the shower. He kept one hand covering his crotch. He did not like being naked among the muscle-bound jocks and hairy men who lifted weights here. They made him self-conscious. The worst part was that they didn’t pay him any mind. They didn’t bully him or laugh at his small penis or skinny body or tell him he was using the weight-lifting machines incorrectly (which he had worried about until watching all the official training videos on YouTube for the model numbers of the machines in this gym). That was why he worked out in the early morning. There were usually women at the gym this early but not many men.
The gym bros were a bunch of macho chads with chins and shoulders and big swinging penises that flopped between their legs like sausages too thick for their casings. His just sort of poked out like an escaping worm. He felt shriveled.
