I have an extremely sensitive sense of smell... Perfume gives me headaches... If it lingers, I am annoyed. I don't like all of that scented crap, no offense... I had an ex that always wore vanilla lotion... I had a headache every time I was around her.
1. yes, I had a girlfriend who wore a certain perfume, and some time later I smelled it on another girl who I was hooking up with and it immediately reminded me of my ex. smell really is the strongest sense tied to memory.
2. I have waited a long time to tell a girl this, maybe its just me, but I don't find perfume, painted nails etc. the least bit attractive.
