This is a fascinating topic because I think BDSM definitely is intertwined with gender and sexual identity.
For me, in the basic terms I consider my "gender" identity as a female, sexual identity as "hetero-flexible/bi-curious" , and my BDSM identity as Dominant "Conscious" Sadist. I do find that my kinky/dominant tendencies do apply to both men and women.
Reminds me of this dog tumbler I look at sometimes.
