Positive comments for The MamaSutraLanae St. John

“I will never thank the MamaSutra enough…for all the very interesting topics she’s got the guts to discuss through her posts. I really wish there were such great sex educators in Europe as well…”

“Some of the most successful and fun sexual experiences I’ve had have always been the most communicative ones, and unfortunately I’ve also experienced the exact opposite of that. So I think it’s pretty f**king cool that you’re all about raising awareness and education.”
