Fuck for Forest (FFF) is a non-profit environmental organisation founded in 2004 in Norway by Leona Johansson and Tommy Hol Ellingsen. It funds itself through a website of sexually explicit videos and photographs, charging a membership fee for access. A portion of funds are donated to the cause of rescuing the world's rainforests. It is the world's first eco-porn organization and may be the only porn website specifically created to raise money for a cause. The group moved from Oslo, Norway to Berlin, Germany following the trial of its founders for having sex in public.

Sexaholics Anonymous (SA) founded in 1979 is one of several twelve-step programs for compulsive sexual behavior based on the original twelve steps of Alcoholics Anonymous. SA takes its place among various twelve-step groups that seek recovery from sexual addiction: Sex Addicts Anonymous, Sex and Love Addicts Anonymous, Sexual Compulsives Anonymous and Sexual Recovery Anonymous. Collectively these groups are referred to as "S" groups since all their acronyms begin with that letter: SA, SAA, SLAA, SCA, SRA.

Sexual Compulsives Anonymous (SCA) is a twelve-step program for people who want to stop having compulsive sex. SCA founding is attributed variously to 1982 in New York City and to 1973 in Los Angeles. Although the fellowship originally sought to address issues of sexual compulsion among gay and bisexual men, and this is still the fellowships predominant demographic, today the program is LGBT friendly, open to all sexual orientations, and there is an increasing number of women and heterosexual men participating. SCA meetings are most likely to be held in urban areas with larger gay and bisexual male populations. The majority of members are white, but vary in age and socioeconomic background. The only requirement for membership is a desire to stop having compulsive sex.
