Someone needs to invent an STP where its basically just a pair of underwear with a packer built into it! The underwear could be made out of rubber (or whatever works) so that when you just stood there to pee, it wouldnt soak through. Somehow the underwear just directs the pee through to the built in packer (which can be made from the same stuff as the underwear) without leaking! You wouldnt want any left behind tho. And the best part is that you dont have to do anything except stand there and pee! And it would work for anyone 😀
