Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes.

In Western society we are bombarded with messages about sexuality from the popular media, and yet it can be embarrassing to talk about our personal sexuality, especially any sexual concerns we may have. Sexual problems can have a ripple effect on many other areas of our lives including intimate relationships with a partner, the family, and work, and our general well being. At the same time all of our life interactions and activities can affect our sexuality The media tends to present sex as easy, good, and spontaneous, and it implies that we should always be in the mood for it. If only sex were that simple. If you and your partner are experiencing problems with sex, you are not alone.

Most women have symptoms of a sexual problem at one time or another. For some women, the symptoms are ongoing. But your symptoms are only a sexual problem if they bother you or cause problems in your relationship. There is no "normal" level of sexual response because it's different for every woman. You may also find that what is normal at one stage of your life changes at another stage.
