Men are also "supposed to" avidly listen to rap and rock music, but I'm gonna go out on a whim here and assume that you rarely ever do that.
I think because perfume smells too light and sweet. I hate wearing scents, but I prefer something with deeper notes and not a light flower like scent. So it's always Cologne for me.
Aftershave, of course. I love Paco Rabanne 1 Million, David Beckham's stuff, Jean Paul Gaultier Le Male and I got this cheap ass Hollyoak's one () years ago that actually smelt really amazing, but it wasn't made expensive, so the smell was gone quickly.
