All the best to you bro, but a word of advise from season adults. If your woman, wife / GF / life-partner is not with you on the wedding and follow their parent's wishes, lots of issues coming your way. Although a lot of people says that marriage is just between you and your soul-mate but with Chinese families, this is really not the case as it concern's many parties.
If your future-in laws are not understanding enough, then seriously few years down the road, probably you will open a thread about divorce procedures. We guys are very patient people but there is always a limit, hit that limit all hell breaks lose.

Bro.... just telling some of issues my frens face before, of course in this case you understand your future wife ( congratz in settling the dowry and ceremony underway ) and your -in laws better than anyone here. Like what you say, you started this thread to get feedback and i believe some feedback can use and some can't ( keyboard warrior la tu ).

Sex before marriage does not mean its bad, to me i feel its a process to know each other physically and not just mentality. Anyway, a free advice for you. Communication between your in-laws well, treat their daughter well and they will repeat ten-fold back to you unless the parents-in-law don't love their daughter.

Bro... dun get me wrong. I am just saying one should get a partner that looks after both side and not one sided.

LOLx bro, you have different mindset la. Sex b4 marriage will ruin it ? Guarantee ? But what you say holds water because current generation fails terribly in relationships. Why ? bcos they are after beauty and physical. Example, 10 men go after a beautiful girl ( the girl will choose the riches one ), all say ' i love you' but in the end that is not love, that is attraction. They are not searching for compability, they are searching for trophy partner or good for piap ( lowyat term ). Which is why you say sex b4 marriage would be ruin but in actual fact its the mindset that ruin themselves and not bcos of sex.

Current generation, most of them don't understand love at all. Guys want pretty / big boobs / slim / obedient / feminine / good in bed girls, while girls want 5C or 6C guys that can provide everything for them then they can flaunt to their friends in facebook. This is reality, if you dun believe me, you tell your gal dun post anything in facebook about your grand wedding ( 1.4K table i think ), see whether she agree or not.

PS
The marriage would be ruin if both of you don't know how to satisfy each other after marriage, that I guarantee.
