The Abnormal versus the socially acceptable:
Lesbians, bi, gays and asexual, BDSM and transgendered people ARE the norm. They have existed ever since human kind has set a foot on this planet (10.000 years ago)!!!! It is only a natural expression of biological and social variety and complexity which seems to be at odds with culture at large.
It is only the social stigma of ostensibly belonging to minority groups that makes us appear different. However, I true- heartedly believe that it is in all of us.
Each person is both male and female - it seems to rather be a matter of degree. Furthermore, each person can learn how to turn pain into pleasure and thus gradually become a mas -o`.
The main difference may only lie in the fact that out-of the closet LGBT people may have been discriminated against. The only things that all of us may have in common are traumatic experiences.
