Orgasm or sexual climax is the sudden discharge of accumulated sexual excitement during the sexual response cycle, resulting in rhythmic, involuntary muscular contractions in the pelvic region characterized by sexual pleasure. Experienced by males and females, orgasms are controlled by the involuntary or autonomic nervous system. They are usually associated with involuntary actions, including muscular spasms in multiple areas of the body, a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm is typically a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin as well as endorphins.
Conventional sex, colloquially known as vanilla sex, is sexual behavior that is within the range of normality for a culture or subculture, and typically involves sex which does not include elements of BDSM, kink, fetishism, and/or happens within a marriage or relationship.

Sexualization is the emphasis of the sexual nature of a behavior or person. Sexualization is linked to sexual objectification, treating a person solely as an object of sexual desire. According to the American Psychological Association, sexualization occurs when "individuals are regarded as sex objects and evaluated in terms of their physical characteristics and sexiness." "In study after study, findings have indicated that women more often than men are portrayed in a sexual manner and are objectified. In addition, a narrow standard of physical beauty is heavily emphasized. These are the models of femininity presented for young girls to study and emulate."

Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a female, the testicles in a male. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Physical growth—height and weight—accelerates in the first half of puberty and is completed when an adult body has been developed. Before puberty, the external sex organs, known as primary sexual characteristics, are sex characteristics that distinguish males and females. Puberty leads to sexual dimorphism through the development of the secondary sex characteristics, which further distinguish the sexes.
