Believe me, I don't do the three things you mentioned, but I think the simplest explanation of all this is: horniness!? People do this because they are horny (in case of cumming into anything) or they get horny doing in (in case of peeing in pants/underwear and showering fully clothed). Just a guess. I think it's hard to understand if you're not into it. Well, should be okay as long as you don't harm yourself or others.

thief @Lee: Sorry, it wasn't quite clear to me. Tied up? You get a muzzle to make sure you cannot bite! :D

I think dangerous dogs get it, so that they are not able to bite. I looked it up ("Maulkorb") and it said "muzzle". Next word is: gag or what?
