I've (37/m) have been dating Marta (31/nb) for a few months now. I've been NM for just under a year while they've been NM since they were a teen.

Marta has two other partners as well as about 5 playmates/FWBs, which I've never had any problems with. I was initially worried that I would get insecure or jealous but I haven't. We see eachother 1 to 2 times a week which occasionally includes overnight visits, things have been going well.

Marta recently told me that they don't get polysaturated and could have up to 6 partners and 12 playmates and they are looking. While I'm not going to pass any judgement as they've been NM a lot longer than me, I do worry it could cut into our time together. With 18 partners total that would give them less than 2 days per month per partner. That does seem like nearly enough to nuture relationships.

I would never tell Marta who or how many people she can date, but I do worry that they might spread themselves too thin and our relationship could suffer. Is there such thing as too many partners? If I'm wrong I'd prefer to be told straight up.
