Me and my partner are very freaky when it comes to sex. We are into BDSM. I'm the dominant partner and he is the submissive one. He likes it very much when I whip, slap, punch and kick him hard. Sometimes he likes me to do it too hard. I have no problem with giving him too much pain because he enjoys it but I hope he doesn't get terrible pain and get injuries. I'm kinda afraid about that. Once, he even asked me to stand on his chest with my high heels on and dig my 5 inch high heel into chest and stomach. He also enjoys licking my menstrual blood. One day I accidentally cut myself with a razor and I was bleeding. I asked him to suck my blood. And he happily did it. Are we normal?
