BDSM involves any of a number of related patterns of human sexual behavior. The major subgroups are described in the abbreviation BDSM itself. There is sexual activity that involves bondage and discipline which is abbreviated with the letters B and D. Then there is sexual activity that involves domination and submission which is abbreviated with the letters D and S. Finally, there is sexual activity that involves sadism and masochism which is abbreviated with the letters S and M. Any kind of BDSM can include these things not just gay bdsm. BDSM also involves informed consent and safety; and is known as safe, sane, and consensual although other people like to call it risk aware consensual kink because people believe that it places more emphasis on acknowledging that all activities, including sexual activities are potentially dangerous. There are discussions and disputes about the meaning and the intent of the terms, but in essence both terms involve all participating in these sexual activities acknowledge and accept some level of risk. Gay bdsm as well as heterosexual bdsm can include some of the following elements. BDSM may or may not involve sex of any kind. BDSM may or may not involve sexual role playing. In addition, a couple may engage in BDSM sexuality while having an otherwise non dominant or submissive relationship dynamic. Gay bdsm as well as heterosexual bdsm many include some of the following activities such as erotic spanking, whipping, paddling, sensory deprivation, suspension, and sensation play in which the couple uses such objects as fur and ice. It seems that this type of sexual activity would involve being trapped in a bdsm dungeon.
It may interest people who are afraid of sexual activity of any kind to know that bdsm activities are practiced by people of all sexualities; therefore the only reason that I can think of that some human beings wish to separate gay bdsm from regular bdsm is because some people are afraid of homosexuality in general which is too bad for them. It is also interesting to point out that most people practice their bdsm activities only in private so they don't share their sexual pleasures with others. The bdsm community can be and often is regarded as a subculture within mainstream society. Therefore, I think that if people talk about gay bdsm instead of just bdsm they believe that homosexuality would be considered a subculture within mainstream society too.
