BDSM in the context of "Sex toy"

Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality. People engage in a variety of sexual acts, ranging from activities done alone (e.g., masturbation) to acts with another person (e.g., sexual intercourse, non-penetrative sex, oral sex, etc.) or persons (e.g., orgy) in varying patterns of frequency, for a wide variety of reasons. Sexual activity usually 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 or enhance the sex life of another, such as strategies to find or attract partners (courtship and display behaviour), or personal interactions between individuals (for instance, foreplay or BDSM). Sexual activity may follow sexual arousal.

Human sexual activity has sociological, cognitive, emotional, behavioural and biological aspects. It involves personal bonding, sharing emotions, the physiology of the reproductive system, sex drive, sexual intercourse, and sexual behaviour in all its forms.

The sex industry, also called the sex trade, consists of businesses that either directly or indirectly provide sex-related products and services or adult entertainment. The industry includes activities involving direct provision of sex-related services, such as prostitution, strip clubs, host and hostess clubs, and sex-related pastimes, such as pornography, sex-oriented men's magazines, women's magazines, sex movies, sex toys, and fetish or BDSM paraphernalia. Sex channels for television and pre-paid sex movies for video on demand, are part of the sex industry, as are adult movie theaters, sex shops, peep shows, and strip clubs. The sex industry employs millions of people worldwide, mainly women. These range from the sex worker, also called adult service provider (ASP), who provides sexual services, to a multitude of support personnel.
