Gordon Thompson frequented the Sports Connection in West Hollywood on Santa Monica Boulevard regularly during its heyday. He had a very nice body, but average for what was normally seen at that gym. The gym was 95% gay men and the average body, and penis size, was often well above the average.
Many of us often felt like we were in the soap opera The Hung and The Rest of Us...
and yes, Gordon did shower at the gym but did not frequent the hot tub. He was average length and rather thick if I recall. He had a nice one. He also smiled at you when he caught you looking at it in the shower!
