In sexology, some people use the term sex-positive to describe an attitude towards human sexual behavior that regards sexual activities as fundamentally healthy and pleasurable, and encourages sexual pleasure and experimentation.

The sex-positive movement is a social and philosophical movement that advocates these attitudes. The sex-positive movement advocates sex education and safer sex as part of its campaign.

It does not make distinctions between heterosexual or homosexual sex, or indeed masturbation for people who are otherwise celibate, regarding these choices as matters of personal preference.
