Dr. Ruth, Westheimer, PhD, Sex Therapist:
God forbid! Don't assume it.
People after 50 should continue to have a wonderful sex life if they so desire, if they say they don't want it anymore, I say goodbye, but if they so desire, but they have to be sexually literate.
A woman has to know that after menopause she needs a lubricant, not to engage in intercourse with a not well lubricated vagina, it's painful, she's going to say, who needs it.
