Rackem Frickidy Frackem Yo!

My boyfriend likes to talk dirty. I don't have anything against it, I just seem to have performance anxiety and have no idea what to say. How do I let go and go for it?
Use Yosemite Sam euphemisms. And shout them out loud! "Johnny, you better rackem frickidy frackem yo diddly dad mo tittily franny tam of a bridily brack!"
It says so much, with so little lecturing: if you're unsure what to say, don't sweat it, say what comes to you, but don't contrive anything, otherwise you sound like a 3-foot-tall moustachioed gunslinger. I was far less entertaining, right? Comics can do anything better.
