Yes, most fountain pens are actually geared towards right handed people.  Most can be used by both left and right handers, but depending on your writing style, for example the angle you hold your pen etc, you may find it slightly easier to use a nib that is angled with a left handed bias. Lamy is the perfect choice for this. They have a left handed nib which can be fitted onto all their different ranges.  So there are lots of pen options here.
