On FetLife, it seems that there have been lots of people shooting down everyone else. It's a fact, people are generally intolerant of others whenever they are not forced together because of outside pressure.
That in itself doesn't bother me. What bothers me are new members of the lifestyle, the kink, who are just entering adulthood (the age of consent), who act as if they know everything there is to know, and shoot down people who have been living the lifestyle for years.
i entered my relationship with my Master before i was 18. When i was 18, i consented to a D/s dynamic, which led to my consent of an M/s dynamic. But i never presumed that i knew everything. i knew i wanted to know more, i knew how we were working our relationship, but i didn't make the presumption that everybody did it one way. i was fascinated by the differences, and at times, envious of them. But what Master and i do works for us, we've always adjusted it to work for us.
We're all different, and folks who are new to the lifestyle would do well to remember that there isn't a relationship (kink or vanilla) anywhere that is exactly the same as any other.
