Here's my perspective. I'm not trying to put a damper on things, just give you an idea of what it's like to be so damned sensitive to odors.
I really prefer that I not be able to smell the person's artificial scent unless I'm so close to him that I'm having sex with him. And if he wears any kind of scent at all (apart from the faintest leftover hint of shampoo, perhaps), he will never, ever get that far.
In recent years, my body has become more tolerant of artificial scents in general, but it really doesn't matter if the product is cheap, expensive, "good-smelling," or "bad-smelling." I've run across pleasant scents that I couldn't detect until I was standing in line right next to someone, and I still wound up with a runny nose and/or watery eyes and/or a sneeze and/or a headache. Fortunately, the effects are less dramatic with certain scents and with lesser amounts.
For those of you who are into women and who hope that your applied scent will attract one: whether they are aware of it, women in general tend to choose mates based on a number of factors; one very important one is natural body scent predicated on genetic compatibility. Axe or Christian Dior or Dire Nasal Assault interferes with this system. I understand that BCPs can tamper with this olfactory ability because they trick your body into thinking it's pregnant (pills apparently didn't mess with me, based on my anecdotal evidence), so YMMV. But covering up your own natural scent messes with the system, too. (If you are pre-T, then all bets are off.)
Men (I suppose straight men) respond to traditionally female odor as well. In keeping with recent research, for example, when I was living as a woman and before I started HRT, my ex was able to tell when I was in the fertile phase of my cycle--I smelled much more alluring to him then.
So when it comes to noses, we can cautiously conclude that women tend to seek out compatibility, and men tend to seek out fertility. I think it's probable that men prefer certain body scents over others (so they might have a preference for women with compatible genetic profiles), but a lot more research remains to be done.
I wonder if anyone has studied how gay and bi/pan people respond to body scents of people of the same sex/hormonal make-up. It seems to me that such research could shed a lot of light on all sorts of cool things.
