A woman has been married for seven years; she practiced masturbation before and after marriage, and she did not know the extent of its danger or prohibition. The marriage was contracted on the basis that she was a virgin, and on the wedding night, she did not bleed from the hymen, so she took blood from an external wound and told her husband that it was the blood of virginity. A year ago, she learned about the prohibition of masturbation, repented to God Almighty, and completely refrained from it. She confessed to her husband that the blood was from an external source, and he did not care about it. Does what she did constitute deception? Does it invalidate the marriage contract?
