I chart online (cuz I'm meticulous like that) and this has now inspired me to chart frag samples too, and see if there's any correlation.
What I'd expect is to prefer the warmer, more gourmand scents pre-menstrually, simply because that's when I'm all snivelly and comfort/chocolate/potato chip-starved.
I've read a bit about women's cycles and blah blah blah and I think I remember something about a woman's nose being the most sensitive around ovulation (due to us being able to sniff out the genetically compatible mates at such a time - seriously!) - but maybe it's just most sensitive to men at that time, and not other things? Also, would this not mean that our noses would be most like a man's nose in a pre-menstrual state? I.e. when estrogen is low? I'm totally speculating here btw - any scientists around?
