me and my partner have been together 3.5 years. monogamous 2, then did some threeways, and now have been trying full poly for a couple months. my only really hard rule is that i don’t want her to get came in when i’m not there. (i also have a cuck kink so i love to watch her get fucked & participate in cleanup) part of it is because of my fetish, but also it feels good for me to feel like there’s a part of intimacy that we only do together?

she didn’t bring it up much at first, but now she’s with a partner who has a penis, and it’s becoming a point of contention for us. she thinks that it’s her body her choice, and i have no say what she does with other partners. i agreee with that for most things, but this is different to me. i’m not stopping her from having sex, i just want her to use a condom when im not there. am i in the wrong?
