That sounds like a line used on him to get into his dirt starfish without protection. Probably went something like this:
Seducer: "C'mon, just let me ram it home without a condom! It feels alot better that way!!"
Clueless guy: "No, I better not. AIDS and stuff, you know..."
Seducer: "PLEEEASSE??!"
Clueless guy: "No, I'm sorry. I don't want to get HIV."
Seducer: "But haven't you heard? If you push out a fudge-dragon right after getting butt-blasted, it cleans out the ol' tobacco road from any diseases! I'm surprised that you didn't know that!!"
Clueless guy: "Yeah, right! Do you mean to tell me that I can let a guy poke my brown eye unprotected, and if I lay some cable right after, I will remain disease-free?"
Seducer: "Thats right!!"
Clueless guy: "Oooooh! That's soooo awesome!!! Just let me run to the kitchen so I can scarf down a quick bag of prunes, then we'll get started!!"
Seducer (to himself): "Yessssss!"
