From Science Daily:
A study of former high-school American Football players has found that more than a third said they had had sexual relations with other men.
In his study of homosexuality among sportsmen in the US, sociologist Dr Eric Anderson found that 19 in a sample of 47 had taken part in acts intended to sexually arouse other men...
...“The evidence supports my assertion that homophobia is on the rapid decline among male teamsport athletes in North America at all levels of play,” he writes in his study, entitled ‘Being masculine is not about whom you sleep with…Heterosexual athletes contesting masculinity and the one-time rule of homosexuality’. It will be published in the journal Sex Roles in January.
Dr. Anderson seems adamant that this is a revolutionary new look at American athletes (and that sex between men must signify a decline in 'homophobia'), but the sample in question may be a little less representative of American sportsmen than suggested.
The 47 men, aged 18-23, were all American Football players who previously played at the high school (secondary school) level but had failed to be picked for their university’s team and were now cheerleaders instead.
Not to be stereotypical, but this isn't exactly an objective pool to draw from. Dr. Anderson did make one interesting observation, though, that we ought to pay attention to:
He believes the positive portrayal of homosexuality on television, the ease with which homosexuals could gradually ‘come out’ by using the internet, the ability for straight men to talk with gay men on the internet, and the decline of religious fundamentalism has made homosexuality and homosexual acts considerably less controversial for university-aged men.
