Why is your wife denying something she isn't giving? This is where I draw the line I marriage. Sex is an integral part of our lives. She knew the type of sex life you lived before she married you, she can’t force you to stop because she lost her interest in that type of life.

I think now will be the time you weigh in why you are still with her. If she's providing all you basic needs expect sex then you should get yourself a distraction away from sexual activity for the time being.

Find new ways to make your wife feel needed outside sex and make her feel alive again. Gradually, her desire for sex will return.

And like I told you before, you need to do some psychological assessment on yourself first. I'm guessing that has more to do with your wife's lack of sexual interest in you.
