My wife [28F] said she never wants to go down on me again and I'm confused on why.

My wife said she never wants to give me a BJ again. I have no idea why she would say that. We've been together for a couple of years and she never mentioned it before. I tried to ask her about it, but she just said she doesn't want to do it again, even though I have returned the favour in the past. She said I don't take care of my dental hygiene, but I do brush and floss regularly. I'm confused about why she would say that and I don't know how to bring it up with her again.<br><br>&#x200B;<br><br>UPDATE:<br><br>First off, thank you to everyone who commented on this and gave me advice. <br><br><br>I sat down with my wife yesterday and talked to her about it and turns out she was in a lot of pain from the way I put my hands on her head and she never said anything about it because she wanted to please me. She said she's been dealing with headaches for a couple of days now and she was just upset because she keeps on pushing herself to please me even though she didn't really want to and it got to a point where she just wanted to stop doing it. In the end, we both agreed that she doesn't have to do it if she doesn't want to. <br><br><br>I (M25) told her to let me know if there's anything I can do to make her comfortable and not in pain but she just shook her head and said she doesn't want to do it again and that's it. I respect her decision but I don't know why she wouldn't want to do it in the first place. I tried to think if I did anything wrong but I can't think of anything.<br><br><br>TLDR: My wife said she never wants to give me a BJ again and I'm confused on why.
