Her name is Ruth Westheimer, but we all know her as Dr. Ruth, the helpful lady who’s spoken to us for decades about sex. She's always direct, to the point, and bubbling with insight about ourselves and our partners.

She also talks candidly about her past experience as a sniper, and shares her thoughts on sex and relationships as we age.
