I can not use diapers because of privacy issues but i came up with something else. Take a 1 quart zip lock bag. About two inches down fold it a little and cut off a small piece on one side. You have to fold it so when you snip it with sissors it forms a small round hole about 1 inch round. Push your cock threw the hole into the bag. Work it in as the hole expands. Next push one of you balls into the bag at a time. now that your cock and balls are in the bag zip lock the bag. It is air and water tight. Let me know how it works.

Dude, points for being creative but that doesn't sound fun to me.
Sometimes I put my dick into a sock, then fold a small hand towel over it, then put a larger hand towel over that and in between my legs, and use underwear or boxers to hold it all in. Can't use it like a diaper, but you get that nice bulky feeling and easy clean up if you shoot your load into it. Thats what I use it for.
