YES!
My boyfriend is wonderful, he is so nice! He was the first one out of his mates to have a steady girlfriend (me) and we've been going out 3 years and still love each other to pieces.
He also plays ultimate frisbee, which is a team game based on niceness. There are no ref's, you have to call it nicely. If someone calls it a certain way, you accept it. His team are great bunch of people, so nice guys can come first!
