If someone is REAL BAD,I'll go fetch my shades out of my gym bag. That'll usually give them the hint if I'm wearing my shades and my ipod.
Frankly, I don't mind a few glances. It helps fuel my workout when I know someone is watching, and I'm among the top 2% nationally for fitness at my age, and compete at the national level, HOWEVER, there's a difference between watching the action from a point of being inspired and tantalized to sexual fantasy. I don't think sexual fantasy nor adoration belongs in the gym.
I'm well known for strutting my stuff, and, have it to strut. Very often I'll have a number of viewers. The regulars are used to me and use me for inspiration. The newbies drool and, hopefully, move on their way. I know I'm elite, and while I don't hide it, I generally don't rub it in anyone's face. Bearing that in mind, I don't consider the vast majority eligible, to be honest. Because I keep focus, and discipline, is where I am today.
No doubt, the gym is a potpourri of sexuality. It's real easy to be "bi" in a gym. And, lots of gay guys do go to the gym, as mentioned above, for a bunch of reasons. Lots of straight guys become "bi" for moments in the gym. That's all just being human. Very few are 100% one way or another.
It is what is. As long as it doesn't interfere with my goals, or become a nuisance, I'll give it to them.
It steps over the line when litte gays start snapping my pics on their cells, etc.
