What is the cause of sexual problems?

Most cases there is not just one cause for a sexual problem; there are often several causes. It is important to look at the problem from three different points of view, namely physical causes, psychological causes and social causes.
Physical causes are anomalies of the body that cause sexual problems. Examples of this are disorders in hormonal regulation as a result of certain medicines that cause a reduced interest in making love, irritations of the vagina that cause pain when making love or certain operations on the genitals.

Psychological factors are feelings, thoughts and perceptions that cause sexual problems. This may be negative feelings for the partner or shame for one's own body, unpleasant events of the past, and also fears and restraints related to sex.

Social factors may be values and standards that you have received in your education, traumatic events or the behavior of the partner. Certain stress factors e.g.: unemployment, a bad financial situation, little knowledge of the body and family quarrels can influence the sexual perception.

Lust :Sex chemistry lasts two years max. And?

Been in a relationship longer than a couple of years? First flush of romance worn off? Well, duh. For some reasonworked hard to identify the specific hormones which downgrade your libido from "passionate lust" to "let's just cuddle".

The team from the University of Pisa, Italy, discovered that hormones called neutrophins are responsible for the slowly diminishing sense of lust, with those in the first flush of romance showing much higher levels.

Dr. Petra Boynton of the British Psychological Society hastened to add that this did not mean the first flush is the best bit

She cautioned that we should not necessarily attempt to revisit that, since the settled relationship feelings can be much more valuable and was concerned that the research would lead to attempts to synthesise these hormones.

Testosterone also increases in loved-up women, and decreases in loving men; couples who had been in a relationship for between one and two years had decreased "love molecules", though the relationships were functioning well. Instead, increased levels of oxytocin, the chemical the induces labour and milk production in new and pregnant mothers, were found in the couples and that's the secure cuddle factor.

I suspect anyone in a long term relationship will be wondering how they can report this to the Department of the Bleedin' Obvious around now
