Your Inner Vixen - From Dr. Laura Berman
In this issue Dr. Berman discusses allowing your body to be submissive to your spouse. That there is something erotic in allowing him to take over.
Her suggestion is to fantasize about being ravaged by your partner and allow your fantasy to take over.
She also suggests that you let your partner in on your fantasy (as long as it is about him) and let him take over from there. He may like to tie you up or tease you.
