A man typically has more capacity to meet emotional needs without his needs being met in return, or so says Dr. Harley. A woman is more likely to feel TERRIBLE about meeting her husband's needs for sexual fulfillment, recreational companionship, etc., if she is not already in love. But a man is less likely to feel terrible about meeting her needs for intimate conversation and affection in that state. He may still feel awkward or reluctant, his emotions may still encourage him not to do it, and/or to be selfish, but it's not as likely to be devastating to him if he does it.

When women go on like this for a long time it begins to take a real physical toll: degradation of mental and emotional state, and health. It can result in a compromised immune system and post traumatic stress disorder, particularly in the face of severe abuse and/or an affair.

Now exactly how long any given person can go on like this varies. It's just that, on average, men can go on like this longer than women before they start to face ill effects. And Dr. Harley has also encouraged some men to go on even if they do start to have ill effects, if it is likely to save their marriage eventually or help their children.
