Semi-open relationship with my fiance, where he can fuck whoever he wants, and I love helping him [FM]

Without going into too much detail of the why’s & how’s, basically the crux of this relationship is that we’ve been together for a few years and engaged for almost a year. The first time we dated we broke up after a few months because he didn’t think he could stay in a monogamous relationship, even though we both felt the best connection with one another. A few months after that we hung out and I wanted to try and make things work, he told me that he didn’t see himself staying faithful and exclusive. I told him that as long as its no strings attached sex, I’m fine with that, because the truth was, his sexdrive was indeed too much for me to handle the first time we dated — so my original reasoning was those girls can be considered living sexdolls lol. He also said his favourite girls were married women, and that getting them to cheat for him was his biggest kink. At that time, he had almost two dozen single girls he’d frequently fuck, with their ages ranging between 18-30 (most skewed on the younger end). And about a dozen married girls, which was a number just bewildering to me; he met only a couple of them through dating apps (which I thought most would actually be from), but most were actually just through everyday-life. I’m 25 and he’s 24.
