Can you get an STI from oral sex?

A big misconception is that oral sex is safer, in terms of preventing unplanned pregnancy and sexually transmitted infections (STIs). It's true that choosing oral sex instead of vaginal sex will prevent unplanned pregnancy, but it only reduces, and does not eliminate, the risk from STIs, like herpes, which can be spread from skin-to-skin contact, as well as other STIs like chlamydia and gonorrhoea. 

If you are going to have oral sex, use a condom to cover the penis or a dam or cut-open condom to cover the vulva or anus to reduce the risk of infection.
