i'd say if she 'simply hates it' then it wouldn't have magically been different before they were married.
If she doesn't like it, she doesn't like it. Don't pressure her. Tell her in a nice way how much you like it, and make sure you make her cum before expecting any pleasure yourself, then she'll feel important to you.
Don't give up on having sex with her at all though. there are plenty of way to enjoy each otehr without her feeling inadequate cos she doesn't like it.
