Usually when a man want to have sex with his wife but wife don't let. It shouldn't harm the dude... after all its just 1 day =)?

But if the man is desperate for sex, I think there is always external factor causing it like work stress, etc, etc. I read about it in Reader Digest where a man want to have sex with her wife to feel "control" and a "winner" because at his workplace, he is receiving a lot of stress by his boss, etc. After a while his wife feel there's no love and doesn't want to have any intercourse with him which cause him to depress. (Wife please understand that when man want and no get, he get depress like a 4 years old kid. So at least reassure him or hint him that its just not today, you will his mood very differently)
