Is it normal that my girlfriend likes to think she's taking my life?

first, getting her toes sucked is the closest a woman can feel to getting head, and two everyone has there kinks. i for one am a submissive, so i like to be tied down and what not, im sure that you have some fetishes as well, hers are just a bit kinkier than normal, enjoy that you found yourself a real freak and see which other types of role playing she might enjoy that wouldnt disturb you as much
