Bob, "relax" means "happy ending". It does not guarantee what kind of happy ending you'll be getting. That depends on the girl, but at least you'll get a handjob for sure.
"relax oriental" means something like "asian massage" or "tantra massage". It's supposed to be referring to the technique but it's mostly bullshit since 99% of the girls don't know how to do it. Just marketing, I guess.
