if you are spending money to be in the audience at a muscle show then it is schmoeing! No matter how one tries to justify it. 
my friend you are missing the point again
there is a great difference between a schmoe and a straight fan of bodybuilding
a schmoe is sexually interested in bodybuilders
an attending fan/visitor/bodybuilder/gym rat is interested in bodybuilding and/or fitness, period.
you are watching this whole bbing scene through a gay lens thats why you cant make up the difference between the two of them
infact i believe you just dont want this clear distinction to exist
clear up your head, you're doing this because you feel alone in this world, alone and miserable
the fantasy generalisation thing you got going on in your mind about the whole bbing world being gay will never be
