Who you need to see depends on why your W feels this way. Has she said? I would probably start with a M counselor who is M positive. He/She can refer you to a ST if necessary.
Is your W in good general health? Her hormone status may be involved, she may be peri-menopausal. She may need to address the PMS with her doc. She may be ticked off with you - any idea why?
Some of the guys here have learned a lot from a book called No More Mr. Nice Guy and works by David Deida. Generally, women aren't sexually attracted to tentative, polite guys. You have to be secure in the validity of your needs and act accordingly.
