Straight men no longer need to prove their heterosexual credentials thanks to a general decrease in homophobia, says Eric Anderson.
Dr Anderson, who has joined Bath University as lecturer in coach education and sports development, has written books on gay male athletes and an autobiography about his life as America's first openly gay sports coach.
"Masculinity is softening, (it is) less rigid and less macho than a few years ago," said Dr Anderson, who has also starred as The Professor in US reality TV show The Real Gilligan's Island .
He was happy to move to the UK. "I became fed up with polarised thinking in the US, the gluttony and (President George W.) Bush, in particular his use of gay marriage as a vote-puller."
But he has noticed one peculiarity. "With gay friends in New York, the conversation is usually about sex, but in Bath it's about which school we went to."
