I'm sensitive to smells and can't deal with a lot of strong perfumes and deodorants or other strong ones.
Even the ones I like can be too much in an incense burner or cologne.
But I do like the smell after rain, moss, the sea air. Especially moss/earth. The smell of the air outside at 5 am. Cold winter smell.
Firewood, roasted chicken, some types of flowers. My partner, he's a very light on smell dude who doesn't sweat much and has something faintly aromatic about him that's indescribable as a smell but it always has a positive effect for me. The smell of fireworks and burnt matches. Citrus. Turpentine.
