My best friend and I ended up moving into a room together our junior year of college and it became inevitable for us to see each other naked from time to time. And yeah, one night it just happened that he was looking at porn when I got home, and like any horny college guy I was interested in checking it out too. We ended up jerking off at the same time watching it and it sort of became the norm and no big deal. I definitely think it made us closer and sealed our lifetime friendship even though we live in totally different parts of the country now.
