So far, I've managed to gunge myself with shaving cream, whipped cream, oatmeal, pudding, cake batter, frosting, s-lube, j-lube and Natrosol. Hoping to add mud/clay to the list at some point.

Underwear and speedos turn me on, too, so I will usually incorporate those as well. I maintain Swimdex, formerly the Men's Swimwear Database, https://swimdex.softr.app/.

If you're going to add me as a friend, at least have a photo or video posted. I use UMD on my phone, so chat doesn't work.
