Sex is fun. Let's start there. But sex comes with issues. Always. When friends engage in moments of passion.... there really should be a binding contract, just stating that everything may or may not change, and everyone needs to be honest and act like an adult after. Stay friends or be lovers, just be cool. How comprehensive and easy would that be? One can dream.Redditor u/Kangheh4533 wanted to know what friends out there were willing to give us a few honest and a few salacious tidbits about their personal relationships by asking.... Redditors who had sex with their best friend, how did it happen and did your friendship change afterwards?
