Meet the boxer. This guy comes from a rough background, who found boxing a great way to vent his energy.
He told me that he used to fantasise and masturbate after seeing other guys with great physiques in the gym showers.

Until one day after talking to another guy in the changing room about (having sex with) girls, he got his number. They used to meet when thier girlfriend were not home, watch and wank over straight porn.
He told me on the third occassion the other guy took a firm grip of his dick and started to stroke his hard on. (and that was 3 weeks ago), will update you as his story develops)
