Yeah, it doesn't look much like a dick, but it works! What I do is wear a packer, and the stp between my legs. It's ridged, so it feels odd at first to walk and sit with it there, but hey, it works and it's cheap. Very intuitive to use!

Easiest STP I ever used. You can use the hard edge of the back of the cup to "wipe" with, and it flicks almost completely dry. If you order from the manufacturer you can get a handy little cotton storage case for it too. Not sure why they don't offer those here.
Definitely not meant to be packed with, and unfortunately doesn't come in flesh tones.
I find myself using this on days when it's tricky to wear an STP in my pants all day, for example when I'm rock climbing. So I just bring this along in my backpack to use when I need to piss. I seriously love these things. I have one in my car and one in my hiking backpack.
