Tried it once and I found it remarkably easy, though I get jealous a lot. But in this case it went sour pretty quickly. Turns out one of the partners was a narcissist and the other borderline psycho. They really deserved each other. At first I was hurt a lot, loosjng my partners and my friends. Now I’m in a relationship with a very caring guy and it made me realise that instead of double the love I got double the madness.
I would certainly by open to polyamoury again, but I am very careful about choosing new friends, let alone romantic partners, after this whole experience.
