People who have a long-term relationship often share that at some point they lack sex drive or experience low sexual desire. There might be many different reasons that cause this and some of them include the following:
Problems in the relationship that are not connected with sex issues may cause reduced sex desire. If you and your partner are fighting about money, family or choirs, this may result in lack of sex drive. If one or both of the partners feel angry, frustrated or even hurt, sexual intercourses are not very appealing.
Sex drive may also be reduced by psychological or physiological issues that have nothing to do with your partner. These issues many include health problems, stress at work, usage of some medications, traumas, etc. The energy you use to solve these issues may be too much and you may just lose interest in sex for some time.
Some sexologists suggest that in some cases the intimacy in the relationships substitutes the passion that is typical for the beginning of a relationship. The lack of passion to fuel your sexual life may cause lack of desire to have sex.
In case you experience low sexual drive, the first thing you need to do is to find the main reason that causes it. After you do this it becomes easier to eliminate the cause and to enjoy pleasurable sexual life again.
