It bothers me

I think it means you should stop worrying about “taking care” of your partner. They probably want you to give yourself a break from worrying. I think they may have accidentally worded it wrong, you shouldn’t overthink it though, they probably accidentally said something that sounds like they’re encouraging you to do the thing while they meant something different. You could ask them directly, I mean you’re partners so you’re intimate enough for those topics, if you ask, tell them to think about the answer for a bit so they won’t get stressed about it and say something dumb under pressure, let them think. I honestly don’t think they meant anything bad. They wanted to make you feel better and stuff but well, they probably never experienced this (I mean idk) and want to help but since they don’t understand your feelings they may word it incorrectly or say something damaging thinking it’s the good thing to say. Explain as much about it to them as you feel comfortable then just let them think, don’t make it weird lol, just a casual conversation. Yeah it’s a taboo subject and all but really, don’t press them to answer you. If you don’t feel like randomly talking about it you have to wait for the moment when maybe your partner brings it up. Either way, you shouldn’t stress about it neither.
