Welcome to this thread BBPB and thanks for your contribution.
I've often wondered about how baseball or football men manage a full bladder with that many people watching. I truly doubt that most of them are too shy. Also, I have the feeling that some of them will "let go" right in their uniforms, even it's just to take the edge off ****** to relieve the pressure. Within the last six months, I know that I have seen a picture of an old urinal in the dugout area of Fenway Park in Boston. I can't imagine that that ballpark would be unique in that regard.
Most professional sports people know enough to try to stay well-hydrated, so that is just asking for a need to sneak a leak. As for him using a cup (as in a paper drinking cup?), I doubt that it mattered if he had to go that bad. Besides, he'd have to come back an empty it later.
Sometimes
http://www.gaymale.ws or
http://www.urinal.net will have pictures of urinals in places like these, or in the case of gaymale.ws a picture of a guy using it or peeing out of his pant leg shorts on the soccer field. HOT!
Why don't you post a picture of this Manny Ramirez and let us fantasize?
