Manhattan has broken a new fad, where personal trainer comes to the bedroom.
The latest trend of coaches is to teach their clients how to have sex, instructing and explaining what to do and what are prohibited.
Among the pioneers of the new discipline in New York as Noa briefs were Eric Amaranth and Amy Jo Goddard.
Each of them has their own favorite, where Eric prefers to stay at the foot of the bed and guide, and Amy gives instructions by phone or better yet through skype, following every detail of the relationship between the couple.
