Come out, come out wherever you are

I just came across this link regarding the lack of out gay men on the ATP tour. I also have wondered when someone will finally have the balls to come out while they are still playing. It's not like tennis is the bastion of testosterone that football is, and it's a one on one competition, so it's not like there's much physical risk involved from getting directly hurt by your opponent. However, there is the risk of sponsorships and endorsements, so maybe that's why no one has come out yet. I really hope it happens soon - it would nice to have an example of a proud, out gay man in tennis.
