Sex clubs , also known as swinger clubs or lifestyle clubs , are formal or informal groups that organize sex-related activities, or establishments where patrons can engage in sex acts with other patrons. A sex club or swinger club differs from a brothel in that while sex club patrons pay an entrance fee and may pay an annual membership fee, they only have an opportunity to have sex with other patrons, and not with sex workers employed by the establishment.
A similar type of club is a masturbation club in which members, either single-gender or mixed, masturbate together in public or private rooms. Sexual intercourse is generally prohibited in such clubs.
There is also a very large and growing group of private sex clubs that, to avoid legal problems, do not operate in a specified location. These organizations focus on private parties in homes or rented facilities and make use of the Internet to build their membership. There is usually a small door fee and most are invitation-only. In addition to sexual orientation, these smaller groups often stratify on specific criteria, e.g., heavy men with beards or those who are HIV-positive. The first sex club of this type exclusively for African American gay men was Black Jack, started in 1986 by Alan Bell. 
Many sex clubs have some form of online presence. Additionally, most adult dating and swinger social networks often provide listings of sex clubs, resorts and events. There is no non-profit impartial overarching organization of sex clubs per se , although NASCA International serves as an umbrella organisation for swinging groups in general.
