hahaha i said YES liao

why ah ? Cuz u see lah , statistic, why got lot of divorce ???? about 50% is because their sex life is not that "fit" / comfortable => they can't cooperate anymore => they won't be able to get along very CLOSE anymore => husband will find mistress ( try other new taste ), wife also like that
=> divorce lah

So I think sex in relationship is equal to love in relationship. You have a great making-love with ur lover is the way you show them how much u care for them ;P care until the lil tiny thing that ppl think it's only " Basic instinct "

My opinion only
