It could be a hormonal shift; or an antiseptic thing; but I'm really sensitive to my smells too. Some I don't mind, some I can't stand, and I can always tell when it's changed because of something I've eaten (for example, I've learned that certain processed sugary foods make it smell all 'chemically' down there).

I'm glad it's still pleasurable, and maybe things will settle down as your body continues to? It must be weird not having the cervix there acting as the back stop, I have often wondered what that would be like myself. And, huzzah for there being no stabbing sensation in the ovaries!
