>>7294935Had an open relationship with my girlfriend for probably around two years. We each had three partners during that time. Not because of any rule system or equality. It just kind of turned out that way. Now i'm still with that girl. We never actually decided that our relationship was no longer "open" but we haven't fucked anyone else in three years mostly because, oddly, the other people couldn't handle it. Lots of insecurity and jealousy and manipulative behavior, especially on the part of one of her guys and one of my girls. Eventually I just said "Look, girlfriend, you know how we roll, you know this isn't jealous rage, but seriously if he does this, or says this, or even thinks about this, i'm going to fucking beat his ass" So we just stopped with that stuff. We've been together for five years since.
All in all, totally fesable among honest open people who genuinely prioritise the friendship of all parties involved over sex with any one member. Which is of course very rare, but still totally fesable and possible. As soon as that understanding falters the relationship(s) go with it
