I use some random soap meant for dogs that very very mildly smells like patchouli. Mostly smells like teatree oil. Some completely natural, completely organic homemade shit with neem oil in it. If you don't know what neem oil is, look it the fuck up. All natural repellent for every type of bug/insect. You can only notice the patchouli in the soap if you're like right up in my shit after I've washed with it it trying to smell me. (Which considering I shower once every two weeks, if that, probably a bad idea to get that close)
I don't use patchouli, myself. As a true SmutPunk (by which I mean dirty fucker) I tend to just go with my natural body stink poorly concealed behind cheap deodorant.
I do that until my girlfriend bitches at me to shower. Like "jesus fucking christ you stink too much for me to touch you, like your very presence offends my nostrils. if you take a shower I'll let you put it in my butt later" "okay"
