Is it normal to abuse your lover during kinky sex?
I am dating a woman right now who is into some kinky stuff. She likes to blindfold me and tie me to the bed and then have her way with me. It is fun for me when she teases me by rubbing up against or groping me and then starts riding me or puts her pussy by my face. One time it seemed like she rode me for 45 minutes or so until she finally untied me and finished me off. That was enjoyable.
However, a couple times other times I was tied to the bed and she put her ass right by my lips, which I thought was gross. When I wouldn't lick her there, she slapped my face, which I couldn't see coming because of the blindfold - that was fairly painful. She then grabbed my head and kept rubbing it up against her bare ass. I also think she was trying to fart while she did this, but I cannot be certain.
I enjoyed the times when she was tendering and loving, but not when she was abusive.
