   Summary

   Gaz wants to know if she enjoys sex before she begins the treacherous path known as Crushes, so she asks the one being out there that would never have any true intentions towards her or get too attached.

   Zim thinks he might enjoy sex with humans a little too much after experiencing it for the first time.
