I do not think this will ever work at all. Even Indian living in the US still do not accept Western Cultures to be infilterated into their ideologies. It is right to know each other as far as possible before tying the knot but for this you do not have to live in the same room & have a sexual affair which is bound to happen. Lets not become like the Westerners who even meet their parents only on Fathers/Mothers Day. It is necessary to have a healthy relationship rather than a flirty one.
