This is an awful analogy because the author is using a scenario with which most hackers will have no familiarity (having crazy sex with a mysterious woman) to make a point about a scenario with which hackers are much more familiar (trying out a different programming language). Any point he wanted to make about Haskell would've been better made by talking about Haskell instead of his sexual fantasies.
Dollars to donuts the situation the author is describing has never actually happened to him.
