When I first became non-monogamous I was having sex with my new love, the man who would become my husband, and my ex-fiance. I was screwing them separately at first, but they both knew about the other and were fine with it. It felt perfect, natural, the way it should be for me, and it made me feel powerful, in control, appreciated. Those feelings continued as I got into MFMing, and being a part-time hardcore Lesbian.
I've only been with five men in my life, and still screwing three of them. The most I ever had at one time was four of them: my husband (does that even count?), my boyfriend/ex-fiance, Lora's ex-husband (she left him to join our family), and the guy who Lora, Clair and I share now as a FWB. It all seem "right."
Yeah, guys like anal and I like DP, so there was that. I always prefer their cum inside me, so after a guy put his first load in my vagina he could go around back after I sucked him up again. It was good because it was all what I wanted.
