I have a similar story. I dated a man for a while and he was known as a man to everyone else, but in the bedroom liked to pretend he was a woman. He let this fetish become another personality, one that only I got to witness and I allowed it to manipulate me. This personality was the opposite of his male counterpart so it left me confused and upset often. It confused me on so many levels, emotionally and sexually. He tried to convince me I'm lesbian because I was open to and eventually into his sexual fetish. It was a horribly manipulative and emotionally abusive relationship. I am now free of this person, but the constant confusion he imposed still leaves me missing him. What a mind fuck. (btw I love women and think we're beautiful and sexy but prefer sex with men, at least as of now)
