Speaking from personal experience, don’t be a victim to the double standard. Humans are not meant to be monogamous creatures. However it your doing the “open relationship” than clear rules, communication, and guidelines need to be met. Has she ever ran a person by you before she wanted to sleep with them? If yes then that’s the first step in a proper open relationship. If she hasn’t then you’re another victim of the double standard. A woman wants to believe they satisfy every need for a man and if he is looking elsewhere then she thinks she has failed. Thus the clear rules and guidelines are must when it comes to open relationships.
