Sex is as much spiritual mystery as physical fact. Sex bonds husband and wife emotionally, spiritually, and psychologically. Buying the lie about sex being nothing more than a physical act brings consequences that are devastating. There are also spiritual, emotional, and psychological consequences. When schoolchildren are given condoms the lie can be reinforced letting them think this will prevent anything bad happening to them.
Some people are dissatisfied and unhappy about their marriage relationship.
They think a little extra-marital affair will provide happiness for themselves. My married lover left his wife for me. So I divorced my boring husband and he divorced his chubby wife. Our marriage was a dream come true. No more lying and sneaking around.
