i'm not up on all the abbreviations, STP?
i've been going into male bathrooms both before and after transitioning. The hook up that would allow me to urninate standing up was out of my reach financially. That being said, men don't try to look over at the guy at the urinal beside him. If they did, it could be misinterpreted as a gay guy trying to see what the other one has.
Standing urination is a big deal for some of us F to Ms. Its part of the male culture, at least here it is. So is showering in a guy's locker room. We are probable more sensitive to it than cis guys, but some transgender F to Ms feel cheated out of part of their life.
I've thought of running a catherter into the end of my penis, coming out the other end and then into my bladder. The problem there would be clamping the tube off once urination was done, not to mention bladder and kidney infections. If I could have that surgery now, I'd do it in a heartbeat.
