heh if you dont know all the ins and outs of anal sex you should not be havintg anal sex. Its one of the best ways to get HIV. And yes you should be protected. Alot of girls ur age not in the porn biz are uneducated about anal sex. One of the reasons you dont see shitty dick in porn if because the girl gives her self an enema before hand to make sure she is cleaned out.
