It really depends on the individual. I'm Asian, I'm not ready to have sex yet, but I know I'll definitely have it before marriage. I can't wait that long, and I'm not even entirely sure if I want to get married! Of course, I won't be telling my parents, they'd kill me, which appears to be the same for other Asians who think the same as me. I have good friends though who are also Asian, and they're defiant on having sex after marriage, but that's purely their choice. It depends entirely on the individual, but most of the time it involves lying to the parents.
