Libido: Loss of libido (interest in sex) can be seen with higher estrogen dose birth control, and usually improved with lo estrogen birth control. Also, it may be important to address other issues such as comfort levels with sex, talking openly about your feeling and needs. See a counselor or psychologist may help. Sometimes their are non-medical issues that need addressed as well.
