My wife and myself have slept around and had previous longer relations as well; I see it as a positive. How do I know what I like from a relation or sex if I didn't shop around? I had extremely bad and incompatible partners/sex and now I know that would never work. When I see people on reddit/twitter talk about their relations, I sometimes wonder if people married or living together actually ever talk; it's so incredibly dysfunctional and broken. And then they wonder why people take off, cheat etc etc as they have 0 bond after being 'highschool sweathearts' for way too long and growing apart for all that time. Few kids 'to save the relationship' of course.
