Human sexuality is the capacity to have erotic experiences and responses. A person's sexual orientation may influence their sexual interest and attraction for another person. Sexuality can have biological, physical, emotional, or spiritual aspects. The biological and physical aspects of sexuality largely concern the reproductive functions of the sexes (including the human sexual response cycle), and the basic biological drive that exists in all species. Physical, as well as emotional, aspects of sexuality also include the bond that exists between individuals, and is expressed through profound feelings or physical manifestations of emotions of love, trust, and caring. Spiritual aspects of sexuality concern an individual's spiritual connection with others. Sexuality additionally impacts and is impacted by cultural, political, legal, and philosophical aspects of life. It can refer to issues of morality, ethics and theology, or religion.

Human sexual activity, or human sexual practice or human sexual behavior, is the manner in which humans experience and express their sexuality. People engage in a variety of sexual acts from time to time, and for a wide variety of reasons. Sexual activity normally results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle. Sexual activity may also include conduct and activities which are intended to arouse the sexual interest of another, such as strategies to find or attract partners (courtship and display behavior), and personal interactions between individuals, such as foreplay. Sexual activity may follow sexual arousal. (Full article...)
Hypersexuality is extremely frequent or suddenly increased sexual urges or sexual activity. Although hypersexuality can be caused by some medical conditions or medications, in most cases the cause is unknown. Mental health problems such as borderline personality disorder can give rise to hypersexuality, and alcohol and some drugs can affect social and sexual inhibitions in some people. A number of theoretical models have been used to explain or treat hypersexuality. The most common one, especially in the popular media, is the sexual addiction approach, but sexologists have not reached any consensus. Alternative explanations for the condition include compulsive and impulsive behavioral models.
The International Classification of Diseases (ICD-10) of the World Health Organization includes "Excessive Sexual Drive" (coded F52.7)—which is divided into satyriasis for males and nymphomania for females—and "Excessive Masturbation" (coded F98.8). A proposal to include a diagnosis called hypersexual disorder, simply describing the symptom without implying any specific theory, is under consideration for inclusion in the appendix of the DSM, but not in the main list of official diagnoses.
