The hurt woman told her online friends that her new husband kept it a secret until she found out on their honeymoon.

She said that he previously kept sex off the card by saying he didn't agree with sex before marriage.

She writes: ''My husband saw my post and says he wants to leave me and sue me? Says he wants an annulment and is considering suing me for defamation of character.

''He says it's only a matter of time before someone leaks his name.

''He saw the post through an old friend of his who knew he had a micropenis and saw on his FB that he had just gotten married.''
