Reason #3: You know who can wear face paint? Clowns. You know who can't? Grown men.
If you like getting your face painted, go to a fair and get a flower drawn on your forehead. Don't be ashamed. Or just wait for Halloween, and slather your grill with colorful makeup, just like all the other children. Face paint doesn't convey passion. In fact, it's kind of creepy. Wear face paint out at night and people will just think you're some kind of pervert or serial killer.
