Beastiality, oral sex, lubricants, etc.......you know, the basics... http://www.huffingtonpost.com/2011/...ach-on-oral-sex-and-bestiality_n_1028670.html
I'm not going to lie. When I had braces, girls used to laugh at the idea of oral sex with me. Although truth be told, they laughed at the idea of oral sex with me even without braces on. And just so no one makes the obvious joke, I was in middle school/high school when I had braces.
It seems shocking that these suggestions are out there, but I see some benefits. I was mortified in college to hear some of the crap that my friends believed, and sometimes they surprise me to this day. I'd rather have people well educated and safe than have to deal with the fallout of some idiot who went willy-nilly spreading disease.
