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.
Hackers not having sex? That's a stupid myth. I would be very surprised if you show some facts showing that hackers have less sex than the average population. Sex is not the point the author, it's just an extra.
Learning Haskell is tough, yet there is still not much demand for Haskell programmers yet. If there are so many hackers interested in Haskell is because there is something else about it along the lines of what the author describes.
