If you believe in the bible than wait, However don't pick and chose what you take from the bible its either all right or all wrong.
Sex is a natural act that every creature does and marriage is just a piece of paper you are no different after marriage than you were before.
I don't recall any animals that have marriage rituals and they are all supposedly gods creations so why is it only humans have to follow the words in the book.
I say if you want to fuck someone its your choice and you shouldn't feel obligated to wait because its written in a book.
