"The research suggests more like 20%.

"In total, 21% of subjects reported sexual attraction to some small children, 9% described sexual fantasies involving children, 5% admitted to having masturbated to such fantasies, and 7% indicated some likelihood of having sex with a child if they could avoid detection and punishment""

Note the key descriptors. "Minors" vs. "small children".
There is a substantial number of adults who have some sexual attraction to mid-teen, postpubescent minors. So what is the percentage of adults who have any sexual attraction to any persons aged 17 (including people chronlogically 17 but looking more like 20 or 25) or any younger than 17?
