Q: It is fun. Previously, they said "Girls will dry on it", and now "Girls will flow on it".
There was no sex in the USSR, so it dried up.

Previously, it was believed when love was real - that a person in love from unshared love ceases to eat, sleep, etc., thinking about the object of his passion. From here and "dry"
in the meaning of "dry", i.e. to lose. And to the sex organs it had nothing to do with it.)
