Yes oh! Some couple are just get together to procreate.Especially in Nigeria, you don't even see your wife's nakedness and you don't know a thing about your favorite things.
Who knows probably people marry only for the sake of procreation. I believe what the C.O should be looking at is the genuiness of marriage certificates and accompaning documents like wedding pics as in the foreign affairs manual and not wether the couples are walking holding hands or not.
