Erectile dysfunction (ED), also referred to as impotence, is a form of sexual dysfunction in males characterized by the persistent or recurring inability to achieve or maintain a penile erection with sufficient rigidity and duration for satisfactory sexual activity. It is the most common sexual problem in males and can cause psychological distress due to its impact on self-image and sexual relationships.
In psychology, libido is psychic drive or energy, usually conceived as sexual in nature, but sometimes conceived as including other forms of desire. The term libido was originally used by the neurologist and pioneering psychoanalyst Sigmund Freud who began by employing it simply to denote sexual desire. Over time it came to signify the psychic energy of the sexual drive, and became a vital concept in psychoanalytic theory. Freud's later conception was broadened to include the fundamental energy of all expressions of love, pleasure, and self-preservation.
An aphrodisiac is a substance alleged to increase libido, sexual desire, sexual attraction, sexual pleasure, or sexual behavior. These substances range from a variety of plants, spices and foods to synthetic chemicals. Natural aphrodisiacs like cannabis or cocaine are classified into plant-based and non-plant-based substances. Synthetic aphrodisiacs include MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects. Aphrodisiacs that contain hallucinogenic properties like bufotenin have psychological effects on a person that can increase sexual desire and sexual pleasure. Aphrodisiacs that have smooth muscle relaxing properties like yohimbine have physiological effects on a person that can affect hormone levels and increase blood flow.

Hypoactive sexual desire disorder (HSDD), hyposexuality or inhibited sexual desire (ISD) is sometimes considered a sexual dysfunction, and is characterized as a lack or absence of sexual fantasies and desire for sexual activity, as judged by a clinician. For this to be regarded as a disorder, it must cause marked distress or interpersonal difficulties and not be better accounted for by another mental disorder, a drug, or some other medical condition. A person with ISD will not start, or respond to their partner's desire for, sexual activity. HSDD affects approximately 10% of all pre-menopausal women in the United States, or about 6 million women.

A vibrator, sometimes described as a massager, is a sex toy that is used on the body to produce pleasurable sexual stimulation. There are many different shapes and models of vibrators. Most modern vibrators contain an electric-powered device which pulsates or throbs. Vibrators can be used for both solo play and partnered play by one or more people. Devices exist to be used by couples to stimulate the genitals of both partners. They can be applied to erogenous zones, such as the vulva, vagina, penis, scrotum, or anus, for sexual stimulation, for the release of sexual frustration and to achieve orgasm. Vibrators may be recommended by sex therapists for women who have difficulty reaching orgasm through masturbation or intercourse.

Sex after pregnancy is often delayed for several weeks or months, and may be difficult and painful for women. Painful intercourse is the most common sexual activity-related complication after childbirth. Since there are no guidelines on resuming sexual intercourse after childbirth, the postpartum patients are generally advised to resume sex when they feel comfortable to do so. Injury to the perineum or surgical cuts (episiotomy) to the vagina during childbirth can cause sexual dysfunction. Sexual activity in the postpartum period other than sexual intercourse is possible sooner, but some women experience a prolonged loss of sexual desire after giving birth, which may be associated with postnatal depression. Common issues that may last more than a year after birth are greater desire by the man than the woman, and a worsening of the woman's body image.
