Related question: In sex talk, how many bases are there and what do they all mean?
There are lots of English-speaking (or English-learning) countries where baseball simply isn't played much if at all. Other sports -- soccer, rugby, polo, cricket -- are likely more common. Since language follows culture, I'm curious: what do English-speaking nations with little interest in baseball use as their metaphor for physical relations? Effectively, I'm asking for equivalent metaphors in other English dialects.
Note that, in the baseball metaphor, there is an implicit "escalation" idea baked into the metaphor. As a "player" progresses from base to base, the conduct associated with each point represents an increase in intensity and/or intimacy. I'm hoping equivalent alternative metaphors preserve this.
