chicagoil: I've learned a few of tricks:
- As guys are undressing, if I'm facing them or are next to them, if I sit down and am putting on or removing my shoes and socks, I can glance up and be more or less at the level of their crotch. This isn't too obvious - if you're dealing with your shoes and look up in this process.
- I walk by guys as they're undressing/removing their underwear. I walk around the locker room (to get a drink of water, go to the toilet, etc.), and as I walk around, I can catch guys as they undress.
- Similar to the above, I can time my walking between my locker and, say, the drinking fountain as a guy is walking to the shower (if he's naked and not covering up). Or as I walk around, I take many glances to the drying-off area outside the showers.
- I also choose the lockers near the sink or the scale - many guys after showering will shave naked at the sink or weigh themselves naked on the scale.
- I choose lockers next to other lockers that have locks on them. Sometimes the guy with the locker next to me will be using his locker when I'm using mine. In the normal routine of putting things in/taking things out of the locker, I move around a lot and can catch glimpses of the other guy's penis. Or I choose a locker in a crowded area (or go to the showers that are crowded).
Good luck!
