I'm not really a pink kind of girl, but I think that men actually find pink pretty sexy, mainly because it's so attached to notions of femininity. The shade seems to make a difference in message, though:
Hot pink: The kind of colour women wear for themselves/fashion
Deep pink/magenta: Comes off as bold, confident
Pale pink: Innocent, demure
Personally, if I wear pink it's more of the pale kind, because I think it's the prettiest.
