If you truly fucked 54 men before marriage and your husband to be (at the time) was so devoid of any sense of emotional IQ that he didn't have a sense on who you were, then he needs to sleep in bed be made.
I'd straight out tell him I fucked over 54 men, and not even including the ones I fooled around with before I married you. What is he going to do, divorce you?
He asked, you answered.
Then do your best Jack Nicholson impression and growl: "You can't handle the truth!" That will smooth everything over and you will both laugh and laugh before enjoying a living room picnic with your kids, before he takes you back to bedroom and gives you another baby.
