Hey, found this browsing the web and I wasn't sure if it had been posted here or not. It's a recent clinical study of tickle fetishism from Gutenberg University in Mainz, Germany. Nothing particularly ground breaking but I thought they did a pretty thorough survey and it could spark a lot of discussion. The PDF version is a bit large so I'll give the weblink.
