Interestingly, the survey reports that among the youngest cohorts of respondents there was more same-sex sexual contact (22% among those aged 16-24 and 26% among those aged 25-34) while a whopping 21% of the youngest cohort self-declaring themselves to be homosexual or bisexual, compared to the overall percentage of 8% in the larger sample.
Go check out the survey results yourself. I thought one of the most interesting results was that 79% of all men said they were "happy with the size of [their] penis" (which is down from 86% which was the result back in 2008!).
Do you think reults would be dramatically different in the USA?
