Curt, you may have explained one observation I made a few years ago. One gym
I went to had the cardio machines facing the aerobics room which had a glass
wall so you could see the aerobics classes.
The women were checking out the gay guys, the gay guys were checking out the
straight guys, the straight guys were checking out the women. Fun to watch.
