That's right Hope, because rugby/football/tennis/golf/cricket are a a hotbed of rampant homosexuality as portrayed in the media etc, aren't they?
Seb, when I was young and spending more time doing sports than doing academic stuff, and showing little or no interest in the opposite sex there were those who assumed that I was gay. As far as I was concerned, they had no idea about what motivated me because they had been brought up to assume that the only thing that could motivate anyone was sex.
Now, I have no idea whether this attitude has rubbed off into the thinking of sportsfolk, but I have sometimes wondered whether the attitude towards sexuality within sport has anything to do with this.
