I personally feel that any cause, specially one like kink that is in its nascent stages, needs its own space to grow, to affect enough people, before it merges with the larger cause of queerness, or sexuality, or even humanity.
Will I write openly about what is or is not done, what is or is not meaningful when it comes to sexuality? Yes. Will I talk about BDSM and kink as a way of life, despite it being taboo for discussion? Yes, I will talk about BDSM and kink, and many other things as well, but I will not evangelise for them.
The point is simple. Intimacy is not about sexuality, penetrative sex, gender, BDSM or any one parameter. Yet, intimacy is about all of them AND MORE.
