There is a method you can learn to pee standing up with lady equipment, but I learned it and I have to say you can't zip down your fly and go, you've still got to pull your pants down butters-style or wear a skirt/kilt all the time. The stream still goes mostly down between your legs, you can get somewhat of an arc to it like someone with gentleman equipment but you'll probably never be able to zip down your fly and pee through there without pissing your pants.
For those interested anyway, you wash your hands, make the live long and prosper symbol (or a peace sign if that works better, you'll have to try that out yourself) with the dominant one, use that to spread, lift, and aim, point that at the back of the bowl, and then piss as hard as you can. If you can't maintain pressure you'll dribble and get it on your leg/pants depending how bad you fumble. It's for the best if you practice in the shower at first, but once you're good at it you can go that way at least at home. (I wouldn't try it in a public restroom considering how far your pants have to come down...) If you're doing it right you shouldn't get piss on your hand but you'll still want to wash your hands anyway.
Kilts are cool and everything but I don't want to wear one every day D: so eventually I'm probably getting an STP... just IDK when I'm purchase shy D:
