I like all ordinary cooking and food smells, and I particularly like garlic. It would be hell for me to be romantically involved with a woman who hates garlic, talk about Hobson's choice! :)
I dislike all the normally disliked smells that everybody dislikes. I think the worst smell ever was when I drove past a chicken farm in IIRC Ojai (north of L.A.) which featured large quantities of chicken "output" and it was a hot day. Note that I'm not referring to eggs. ;)
I like perfume and cologne when used in reasonable quantities. I sometimes use after shave myself but only in very small quantities. I think there's a problem with sense of smell fading with age, which sometimes results (at least as I have noticed) that some older women tend to over-use perfume. And there's always the natural tendency to become accustomed to smells, that the person who wears it doesn't realize how strong it is because after you apply it your nose naturally adjusts and quits sensing it. That is why I use such a small amount of after shave when I do use it. I know it will smell stronger to other people than it does to me.
I like incense and scented candles although I haven't had either in a long time.
I would be tempted to use garlic cologne except that I know that would be just so wrong!
Might be handy if I dated an attractive vampiress.
