If its not fixable, or not wrong, then why ask for help.

And yes it can be as simple as asking if you are actively seducing your wife.

Think about it this way:

1. How successful were you before getting married in seducing women?

2. If you were what changed after you got married?

3. If you weren't could you be missing some skills?

I'm of the belief that regular sex, while a reasonable expectation, is not a guarantee. Women have to be actively seduced to receive sex, and it becomes even more important after marriage.
