Sex is synonymous with the success of a relationship/marriage. However, during every couple’s life together there will be times when there are sexual problems. These can occur for a myriad of reasons, perhaps as a result of illness or because there is a natural occurrence in one partner’s life (such as lowered desire after a woman gives birth). Often it’s just a case of patience and understanding, but sometimes people can get worryingly out of step sexually, and this can threaten the whole relationship. The truth is, both men and women tend to complain about the same things when it comes to sex, particularly when they’re in a long-term relationship.
