Obtaining backup options while in a relationship is one of the main theories preached to men in ltrs on TRP. The belief that a man should keep as many possible prospects open to him while he is in a relationship is important to keeping abundance mentality. Although the idea makes perfect sense theoretically, I am still confused as to how I should go about implementing this notion while in a relationship. How is a man supposed to keep another girl open to the idea of having sex with him even though he can't physically pleasure her in the moment? How is he supposed to openly flirt with women/get numbers without being accused of trying to cheat? I'm not in an ltr right now but if I were to ever enter one in the distant future I want to be prepared as much as possible. Thanks for the advice as always.
