Student question - Is serotonin a Cupid?

[Drnanjo]

Biotipsters,

I am getting many good student questions posted to my Psychology Blackboard.  
One of the most recent concerns the role of serotonin in sexual attraction -- 
that is, does serotonin play in any role in promoting attraction between 
people?  Do any of the physio people know if and what the role of serotonin 
in physical attraction is, so that I can post an intelligent (or reasonable 
facsimile thereof) answer to this query?

Thanks much.
