Yes I also think thats true. Pick up coaches are telling shit and want to sell their shit. Maybe on the short term that pick up teachings are good for experimenting and get in contact with more than one girl/man per year and explore the basic sexual needs and behaviour of the opposite sex, but I think on the long term most people truly want a long lasting intimate and honest relationship.
I think especially honesty is a quality everyone deep down knows is a important part of a healthy relationship. Sharing even the ugliest truth about oneself with the partner is a powerful way to really connect and a deep level. But what do I know, never had such a relationship.
