My experience has been that a man will find any fragrance a woman chooses to wear sexy if he finds her desirable to begin with, presuming it isn't a perfume that really makes him gag. It goes with the whole package. There are plenty of male perfumistas on Basenotes, though, who may disagree with me - but I think they are the exceptions.
Example, my first husband loved Ambush (which I always thought of as a horrible stinky perfume - old lady, cheap 'ho, you name it. And my apologies here to any Ambush lovers). Reason: the babysitter that used to watch him and his younger brothers and sisters when he was 13 years old wore Ambush. And to his 13-year old awakening hormones she was the epitome of sexiness and desirability. Years later, he still thought it was a sexy scent. It's all in the mind.
But, again...Basenoters may be the exception to this because they are already discriminating before they even meet the woman they will find sexy. They may even be turned off by a woman they would ordinarily find attractive if she wore a scent they didn't like, though, er...maybe not. It's possible that my experience is the exception to the rule.
Sorry...I'm not a man. I'm a woman in my 40's. I have owned and worn Lauren and Opium, but never garnered many compliments on them. My current (second) husband likes Fracas, and the other night he complimented me on Mitsouko. But he doesn't like many perfumes at all. I have always thought Opium is a very sexy fragrance, unfortunately it doesn't work as well on me as I've smelled on others.
