Exactly. Anytime you see polls or stats on reasons for divorce, intimacy is always in the top.
Great sex can't save a marriage, but no sex is a great way to lead to divorce.
I disagree. In every statistic I've seen, in every poll I've seen, sexual incompatibility rarely made it into the top five reasons for divorce.
The most common things found among the top three:
InfidelityMoney
Physical, emotional, or psychological abuse
Growing apart/different values/loss of respect
Any and all of these things can affect intimacy. But the fact is that the initial raw passion does cool over time, though sex can be and for many couples is precious and special all the way into the sixties, seventies, eighties. Raw passion or great sex is one of the worst reasons to get married.
