My submissive nature stems to my teenage years. My stepbrother found cocaine in my room and blackmailed for sex. Long story but my mum was  broken after her first marriage failed and i couldnt let her find out. I was 17 he was 18. We had secret sex for 6 months till he left for university. After a while it became routine and increasingly he dominated me. Since then sub/dom sex is only way i can cum. Married for 20 yers now but have had two affairs with dom men that leave me exhilerated.
