If a husband is getting all his needs (physical, emotional & spiritual) met by his wife, he will not look or even be attracted to other women. That is why God said, he will leave his father and mother and cleave to his wife.
If a husband needs are being met be his wife, he will be blind to the temptations that are thrown his way.

Why do I say this, because being married for nearly 21 years I can say two things.
One is I know for a 100% that our Father knows everything and has my best interest at heart. And second the best times I was immune for female temptations was when my wife was fulfilling my needs. She, my wife, was only one I lusted after the whole day, my thoughts were on her the whole time. Other women didn't have any affect on me, because I was so connected to my wife that I was in a way blind to see what other women have (sex) to offer.

So I will trust my Father and His Word (the Bible) to keep me safe.
