I think we are starting to see the puritanical ways of being ashamed of our sexuality slowly diminish in society. The more that happens, the more PE will become accepted.
I think this is only generated through a positive [self] belief ( Beginning in the family unit, Where a Father and Mother are open of their sexuality. Thus creating the environment which will display less shame )
PE will not become more accepted until FEAR of sex is lost?
Men’s lifelong fear is and will always be sex?
