heuristics or lack of it

The ongoing debate about chics being sweet or not will not start or end here. But someone is gonna clear it up. Sometimes you pursue someone with all your zeal only to belittle the eventual reward.
Surely there must be signpost that point to the taste of the pudding.
I was talking to a friend of mine who is currently seeing (or if you like .......) a hot chic. Apparently he says that he's better off masturbating.
Otherwise this 'no sex before marriage' will be useless and divorces or infidelities will kick in

Chics also talk abt some heuristics: the shorter the monkey the longer the tail.

Any ideas?
