Q&A: Have you been tested?

QUESTION: Dear The Phuket News. A friend of mine recently told me that having unprotected oral sex with a partner was not a big deal as most diseases were caught by having intercourse. Is oral sex without a condom or dental dam (female condom) safe? Also, in general, is there any place she can be tested for STDs anonymously as she is scared of the reaction her parents might have?
