We have members who were sexually abused as children, and others who've been raped or otherwise have suffered from injury or pain related to sex. So for us, it's not about "sexual repression" as it is in keeping with our core mission. We don't think it's too much to ask people to not engage in sexually explicit and sometimes pornographic conversations on a mental health website.
There are no lack of online communities you can join to engage in explicit sexual conversations. We are no longer one of them.
