Are you about to be married? If you only have sex on your mind, then go ahead and grab her and say ‘finally we are all alone’. It it were I/me, however, I would ask her what kind of champagne she would like me to order from room service.

i do not know the axact one, but here i would like to try my best " the wonderfull meeting between the two persons in opposite gender after the wedding ceremony is done we usualy call it first night in the heaven".

I think I said “Oh God, my feet hurt. Thank God I can take these shoes off.”
