Hey, this is as valid a question as any other about dinosaur appearance.  
Let's just not let this one degenerate...

As I understand it, as all the genitalia, male and female, are found 
within the body cavity in both crocs and birds, that is generally 
assumed to be the case in non-avian dinosaurs.  In fact, structures on 
the cranialmost chevrons of some dinosaur specimens have been interpreted 
as attachment sites for penis-retractor muscles.
