congrats, its a great feeling and Mr. Hockey, you can use it even without a stp, I didnt have a stp when I used it, just went into a stall, guys dont really care, they go in, do there thing and go out, no talkin or anything and plus some guys do sit to pee, no one really thinks anything of it, and some guys are "pee shy" and like to use stalls to pee in, personal preference, I do want to try a stp though
