What do you need to quickly not finish? We understand the reasons.
Instilled by Hollywood masterpieces of an erotic-adventure nature, the incentive to believe that sexual intercourse is LONG, no matter how sorry, is just a myth. The fact is that a person must constantly improve himself by overcoming natural instincts. People constantly should not do something, and they are ready to look for ways to solve the problem, overcoming what was once laid down in the subconscious by nature. For example, not to sleep after dinner, so as not to be fired from work (natural instinct says: eat - sleep). Or not eating too much so as not to get better (natural instinct says: eat as much as possible to be ready for starvation). And finally, do not finish during sex for as long as possible to please your partner (natural instinct says: have sexual intercourse as soon as possible, until something prevents you from conceiving an heir).
