Never really attempted to write to them. Just had fun going through their profiles and such. And yea, sometimes I really wonder. If I know they're gay, those who has their photos posted would've exposed that they too have viewed other people's profiles.
My point. If 2 persons who know each other are gays, wouldn't a nod or a smile be better than to act as if you don't know each other? And they're just working out next to each other.
Or maybe I guess, they're just avoiding awkwardness. I know I had. Still avoiding the muscular man whom I communicated with, and turned out not being his type and was told that in the face. Or maybe it's just me. Need to be more narcissistic next time. ;)
