Sexual partner in the context of "Term of endearment"

Masturbation is a form of autoeroticism in which a person sexually stimulates their own genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. Stimulation may involve the use of hands, everyday objects, sex toys, or more rarely, the mouth (autofellatio and autocunnilingus). Masturbation may also be performed with a sex partner, either masturbating together or watching the other partner masturbate, known as "mutual masturbation".

Masturbation is frequent in both sexes. Various medical and psychological benefits have been attributed to a healthy attitude toward sexual activity in general and to masturbation in particular. No causal relationship between masturbation and any form of mental or physical disorder has been found. Masturbation is considered by clinicians to be a healthy, normal part of sexual enjoyment. It is found to be harmful only as a result of certain medical conditions such as Peyronie's disease and hard flaccid syndrome.

Romance or romantic love is a feeling of strong attraction towards another person, the mental state of being "in love" focused towards forming a relationship (or pair bond), the courtship behaviors undertaken by an individual to express those feelings and resultant emotions, and the practice of initiating relationships based on passionate feelings over more practical or ordinary concerns. Romantic love is considered to be a motivation or drive, which is distinct from (but related to) the concept of attachment.

Collins Dictionary defines romantic love as "an intensity and idealization of a love relationship, in which the other is imbued with extraordinary virtue, beauty, etc., so that the relationship overrides all other considerations, including material ones." The concept of romantic love also came to represent the idea of individualistic choice in marriage and sexual partners, although it's rarely realized fully and can be a source of both gratification and disappointment in relationships. The terms "romance" and "romantic love" are used with multiple definitions, which can be contradictory at times.

Sexual abstinence or sexual restraint is the practice of refraining from sexual activity for reasons medical, psychological, legal, social, philosophical, moral, religious or other. It is a part of chastity. Celibacy is sexual abstinence generally motivated by factors such as an individual's personal or religious beliefs. Sexual abstinence before marriage is required by social norms in some societies, or by law in some countries.

Abstinence may be voluntary (when an individual chooses not to engage in sexual activity due to moral, religious, philosophical, or other reasons), an involuntary result of social circumstances (when one cannot find any willing sexual partners), or legally mandated (e.g. in countries where sexual activity outside marriage is illegal, in prisons, etc.).

Sexual stimulation is anything that leads to sexual arousal or orgasm. This thing can be physical or of other senses, and is known as a stimulus.

Sexual stimulation is a broad term, usually understood to mean physical touching of the genitals or other body parts. The term can, however, include stimuli affecting the mind (sexual fantasy), or senses other than touch (such as sight, smell, or hearing). Sufficient physical stimulation of the genitals usually results in an orgasm. Stimulation can be by oneself (masturbation or sexual fantasy) or by a sexual partner (sexual intercourse or other sexual activity), by use of objects or tools, or by some combination of these methods.

Orgasm (from Greek ὀργασμός, orgasmos; "excitement, swelling"), sexual climax, or simply climax, is the sudden release of accumulated sexual excitement during the sexual response cycle, characterized by intense sexual pleasure resulting in rhythmic, involuntary muscular contractions in the pelvic region. Orgasms are controlled by the involuntary or autonomic nervous system and are experienced by both males and females; the body's response includes muscular spasms (in multiple areas), a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm (known as the resolution phase) is typically a relaxing experience due to the release of the neurohormones oxytocin and prolactin, as well as endorphins (or "endogenous morphine").

Human orgasms usually result from physical sexual stimulation of the penis in males (typically accompanied by ejaculation) and of the clitoris (and vagina) in females. Sexual stimulation can be by masturbation or with a sexual partner (penetrative sex, non-penetrative sex, or other sexual activity). Physical stimulation is not a requisite, as it is possible to reach orgasm through psychological means. Getting to orgasm may be difficult without a suitable psychological state. During sleep, a sex dream can trigger an orgasm and the release of sexual fluids (nocturnal emission).

Fellatio (also known as fellation, and in slang as blowjob, BJ, giving head, or sucking off) is an oral sex act consisting of the stimulation of a penis by using the mouth. Oral stimulation of the scrotum may also be termed fellatio, or colloquially as teabagging.

It may be performed by a sexual partner as foreplay before other sexual activities, such as vaginal or anal intercourse, or as an erotic and physically intimate act of its own. Fellatio creates a risk of contracting sexually transmitted infections (STIs), but the risk is significantly lower than that of vaginal or anal sex, especially for HIV transmission.
