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.
