It seems such a function does not exist, as you can see on this
page of the manual (rings a bell ?)
http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Kernel_23_ref/Function_intersection.html
You may make do with the intersection described in the above web page,
though.

As for the orientation you want to give to an intersection, I must admit
I have never come accross such a concept, and I present to you my most
sincere apologies for not understanding this.
