The fault isn’t with desiring intimacy. Do you think women never desire intimacy? Do you think married women who have brought life into the world never want intimacy?

Men also can’t expect their wives to be open and available for sex if there isn’t a level of respect. Not being involved with child rearing and the house is showing his wife that he doesn’t care to help. That he doesn’t care enough about HER to be willing to help. THAT is usually a key part in not feeling loved and in turn killing the intimacy.
