I am sorry there are incompatibilities between you and your wife. We can feel very deceived when those we are closest to are not honest with us in the beginning. You sound a bit shocked; I would be, too, if my partner had kept such information from me.
I strongly suggest couples counseling. I think it's possible to work things out between the two of you. Coupling involves compromise at times, and I think you both can find a common ground, with some help/support from a couples counseling professional.
I wish you healing-- for you and for your marriage.
