A new study out of Bath University shows many straight and gay men kissing asexually in Britain:

Based on in-depth interviews of 145 British university and high-school students, Anderson and his colleagues discovered that 89 percent had kissed a male heterosexual friend on the lips at some point. A total of 37 percent had engaged in "sustained" kissing with another man, Anderson said. The men all identified as straight, and they didn't see the kisses as sexual.

"These men have lost their homophobia," Anderson said. "They're no longer afraid to be thought gay by their behaviors, and they enjoy intimacy with their friends, just the same as women."

Also, contrary to stereotype, athletes were the most likely demographic for snogging.
