WEAR GLOVES.
(Seriously: They're required for competition fencing anyway... get used to them - more than anything else they'll improve your fencing if the fit is tight.)
But on that same note, left handed fencers are out there - you're going to have to face them, and you might as well take a lesson from what he did to you... namely, hit you in the hand.
The reason everyone complains about left handed fencers is because of how open and unprotected the right side of your body becomes. But really: they don't have an advantage over you save that they fence with that side of their body unprotected more often.
Personally, I always vastly preferred left-handed opponents (and yes, I'm right handed). Why? Because my primary target area was always the hand and lower arm. That's just easier to hit when your opponents weapon is on the same side of their body as your weapon is - in a line.
So, start working on your bell guard action, your stop cuts and buy a glove.
