To me, Prada (original and Tendre) are not sexy scents. They are great for everyday and for work. Smells wonderful and not distracting. I haven't tried the intense version, so I cannot comment.
I would classify Coromandel the same way. It does have the Chanel qualities and yes I would categorize it the same as Prada, everyday and very wearable to work.
I guess that if I wanted to project sexy, I would be wearing the likes of Agent Provocateur, Narcisse Noir (oohh, la, la) or Fleurs D'Oranger.
