Sex before marriage is fine unless you're very religious and do not believe in pre-marital sex.

But I do not encourage casual sex, and sex with multiple partners. Let me stress on using protection as well. We asians use to be quite proper till recently, now you can't even use that excuse. Kids these days all have sex at a younger age.

Since there's nothing we can do about that, we can at least educate them on the consequences of doing so.

Sex before marriage is absolutely necessary. Gotta see if you're sexual compatible with the girl before marrying her. Who knows? She might not be kinky enough, or she might not want sex more than once a day or something. That could be a problem.

So it's always a good idea to see if a couple of sexual compatible before marrying.
