Man o man, I'd be doing whatever I could to suck my own dick omg dude you are HOT and hot legs too. Try leaving that cream inside for awhile to let it get glued up and thick and see how your bladder deals with your piss accumulation as you forget about it until ....you're standing, or sitting there for half an hour waiting . That's fun bro
Fuck the cath, just stick the nozzle into your pisshole so it's seated and send it in. You'll LOVE the sensation going in, all cold and parting your urethral walls then touching your sphincters. You'll twitch in surprise when it happens and open them reflexively, relax, don't fight it. It's hot af.
