On the topic of girlsmell, which is my thing now I guess, there was this one time where at a larp summer camp I went to, some of the people in the predominantly male dorm used my room as a hangout spot to escape the overwhelming plague of boysmell in the dorms, as my room was the only spot free from it. I was a bit annoyed they did it without asking, but I wasn't there at the time, I would've let them if they asked, and the curse of boysmell is an emergency situation. More importantly, it was pretty affirming consider I did not have even an ounce better hygiene practices than any of the boys.
Looking back on it, I wonder if putting my panties in front of the industrial fan someone had brought and was using to cool the dorm down would've helped, especially since some people had issues with febreeze and stuff, but that would've been highly out of character for me, considering I've basically always come off as ace unless asked about it. Probably because I've never had a single good experience talking about sexual topics since I was an elementary school boy joking about it in the back of the bus with another elementary school boy who quite literally didn't know sex was how babies were made until I told him.
Anyway, I've learned my lesson through the power of hindsight and will consider the possibility of using my panties if ever I'm faced with a similar scenario.
