I am a mid 50’s married guy with real-time experience in our local BDSM scene. I’m not a sadist, but do have a kink for consensual control and mild degradation. Paraphrasing from a friend on BDSMLR:
Feminism, however you choose to practice it, is not just about insisting on equality but also about your own sexual autonomy.
If you like to be used and degraded in bed, it doesn’t make you less of a feminist. If it suits you, you can crave and invite both verbal and sexual degradation from your partner, where and when you feel comfortable doing so, never allowing the same treatment outside of the bedroom.
The mantra, “My body, my choice" allows you to practice your sexuality however you choose.
