A big nose. That's what I really like on a man. I've had to stop referring to my heroes' 'aquiline features' because it was becoming so predictable, but if you read a story of mine that doesn't mention them, just take them as read.
In my forthcoming Lust Bite, Honeytrapped, I'm silent about that facial focal point on Calum, the tango-dancing hero, but when he places his forehead against that of his partner, you can be sure that their nose tips will be touching.
So, yes. Alan Rickman, Richard Armitage, Barry Manilow...OK, maybe not Barry Manilow. But the nose has it for me.
