Like men, they do have a higher level of arousal with a new partner. But when interest in sex lessens, it's often because a man is not giving them what they need emotionally or what they need during sex. Women say they don't get enough foreplay, or cuddling, or whatever makes them feel connected. You need to figure out whether you are adequately available in this relationship. It was totally out of the blue.
Men can be fairly clueless.
I commend you for paying attention to this and wanting to do the right thing. Drew Pinsky, M.D., is co-host of MTV's Loveline . 1000 Wilson Blvd., Arlington, Va. 22229. All rights reserved.
