I agree with Squirrley. Life's too short. Have fun for crying out loud. You never know until you give it a shot. And if she IS 20, 6 years isn't THAT much of a difference. My girlfriend is living with a guy 13, (yes THIRTEEN) years younger than her and they are happy as could be. I'm not saying it's for everyone, but what have you got to lose? Better to do something then to sit around wondering, what if?, right?
