Using barrier methods, including condoms and dental dams, is the best way to make oral sex safer. A lot of people who are worried about dealing with bodily fluids find that flavored
condoms and dams also reduce their inhibitions and make them better at going down on their partners.
If a man ejaculates during oral sex in or around the mouth of his partner or if any ejaculate gets in his partners eyes, it greatly increases the risk of STD infection (if he is infected with an STD).
In many cases, a STD can be transmitted even if the penis or tongue doesn’t go all the way in to the vagina, mouth or rectum and even if it isn’t obvious that body fluids are exchanged.
Some educators suggest you avoid brushing your teeth prior to performing oral sex as you can cause small cuts or abrasions that could increase the risk of fluid transmission.
