I quite enjoy perfumes and other fragrances people put on themselves, just not all of them, nor do I bother to actually keep it as an interest. I guess my olifactory sense is also a bit sensitive, since I avoid any perfume department in stores (and clearly avoid any kind of perfume stores as well) since that's a frontal attack on my scent. I can deal with sweet scents fine, but not when they're mashed together all at once. It's like a glittery cloud of thunder zapping me in the nose.
Interestingly enough I do have a certain "feel" for scents and overall, I get told I smell pretty nice when it comes to using stuff like deodorants and such, since I apparently have a nose to buy ones that aren't an all out assault, but just a slight scent in the background. I've ended up receiving deodorant from my parents in the past, only to throw them out (or ask if my dad or other family wants them) since I didn't think they smelled good; some were just too much.
I actually ended up going shopping for fragrances with girlfriends in the past often to help out to pick something nice and subtle.
Besides that; I do like the smell of gasoline at a station (and sometimes at a garage as well), petrichor (the smell of rain on dry soil), bacon... those are a few that come to mind. The smell of static electricity is a bit of an odd one for me, as I'm not sure if I like it or dislike it... but it does help me at times to avoid getting zapped, lol. Good for me to at least recognize it
