Here the question
Why do some people need to look elsewhere when they are in a relationship and in love?
If this has ever happened to you, could you explain to me why, being in a relationship with a person you love, who you are extremely physically attracted to and with whom you like to spend time, do you still have this need to maintain a relationship of a purely sexual nature or a one-night stand with one or more other people? What makes your main person you are in love with "not enough" for you and that you need to look elsewhere, even if these third parties represent absolutely nothing to you and are possibly even less attractive than the person you are with?
There is no judgment in my question, I would just like to understand the driving force behind wanting to be sexually active with other people, even if you are completely satisfied in your main relationship.
Beside this aspect that I don’t understand, my relationship is pretty perfect
