There are various alternatives as to how you want to show your Actors interacting with the objects in the sequence diagram. Let us suppose that one of hte Actors initiates the Use Case, and the other is 'reactive'; that is, this other actor receives information, and may respond in reply, but cannot initiate any sequence of events. This can readily be shown by Rose sequence diagrams, with the first Actor initiating the sequence, and the other actor behaving like any other object in the sequence diagram. Hopefully, this is what you want to do, and I would advise ensuring that you don't try the alternative unless you're sure that's what you really need to do... Let us consider an alternative scenario, where both Actors want to initiate activity. Strictly speaking, this cannot be a single Use Case - there can only be a single initiator to a Use Case. However, UML allows the description of such a situation in a single sequence diagram - this enables the depiction of asynchronous, multi-threaded behaviour. You will find it hard to coerce Rose to show such behaviour in a satisfactory manner.
