I'm thinking of sadomasochism or just straight-up insanity
How do you know?
I like the thought of getting whipped by someone who likes me. I like the idea of having all my dignity taken away from me
It is ok to share your plans with others to get another opinion. You should keep bedroom stuff in the bedroom.
My partner agrees with this fantasy. If I wanted your fucking opinion, I would have asked for it.
No need to get angry. If your partner is up for it and consented, then you should do what makes you two happy.
