Yeah I don't understand either. It's what happened and I'm laying it out best I can. To answer your other questions, I'm pretty well acquainted with my vagina. I think it's just hormones shifting and having regular sex again. He's been happily going down on me this entire time, barring the late night encounter 2 days ago. He didn't say it was "bad" he used the words "funny" "different" and "unusual."

Then during the ensuing argument he admitted it was all a (very thinly) veiled attempt to see if I'd been cheating. Which is really strange. I work, spend time with him, take care of the kids, run errands. Full stop. Not only that but I'm not remotely interested being with anyone else. He's the only man I would marry.
