Ok so the title sounds insane, but me (19F) and my boyfriend (20M) have been together for 2 years now, we have a really healthy relationship, except for some things that have been happening lately and are changing my perspective on our relationship

Back in february we had sx (i dont know if I need to censor, i'm new here) and when we finished, while he was showering, I saw there was a poop stain in my sheets. Not just a poop stain, but it was textured, a small textured stain. It was definitely his because I clean myself properly, also I had just showered, and he openly said he was gonna take a sht in my bathroom right before we did it (we're really close and share these stuff). Anyways, I was absolutely shocked. I spent the rest of the night kinda weird to him, not on purpose, I just kept thinking about it. I know he's clean, we even joke about straight men who think cleaning themselves is "gay" so that is definitely not the case, he really isn't like that.

I haven't told him about it, I removed my bed sheets to wash them like i almost always do after we do it because, yk, sweat and stuff, and just washed it off. Never told him to this day because I was scared to embarrass him. I think about it almost every day, it haunts me to this day, hygiene is absolutely essential for me and it disgusts me to think about it.

Another thing, I recently found out he doesn't floss. At least not regularly. I can't even kiss him the same way like i did before, this may sound dramatic, but I also didn't floss regularly until I was like 16, and now I can't go 2 days without flossing without feeling disgusting, because it really is gross when you don't do it.

I asked him to start flossing because it's important as hell, he said "he would for me", which I think it's weird. the way he said it was highkey unserious and i know he won't.

Just to clarify, he doesn't have any mental difficulty, like depression, that makes it hard for him to do basic tasks or take care of his hygiene, he is totally neurotypical and mentally healthy etc.

I really dont know if i should have a serious conversation about it, I don't think im attracted to him like before, everytime I think about us being intimate I just think about him not flossing and the poop incident, and i feel so bad but it's really affecting me, he has no idea about it. I always communicate but this feels way harder than anything else. I can't really imagine us being intimate again, at least not like before. AITA for feeling this way? Should i talk to him about it? How?
