NelsonMuntz: "-straight guys who are overly obsessed with gay sex"
This is rampant in bodybuilding and powerlifting. Some other people are like this too. I have always thought someone who chronically jokes about gay stuff is gay or gay-curious. If I recall correctly, Jason Pegg (who I think posted here) and Jim Wendler were incessantly posting gay-flavored pictures, memes, and statements on FB and elsewhere. Why would have gayness on the mind when not presented with the topic or having to interact or see gays.
Strange...
