you say betrothal or i see wrongly? I never heard of arabic betrothal culture.
I used to stay in the kampung and witnessed several cina betrothal ceremonies. The future 'bride' will still be living with her family, nobody can bullshit me on this.
You defence of the 'LUST' is getting weaker. Most of us know Muhammed has a colorful (sexual) life and slept with many women.
