No – you cannot become pregnant from oral sex; however STDs, including chlamydia, gonorrhea, HPV, herpes, hepatitis B and syphilis can be spread by giving or receiving oral sex if your partner is infected.There is a small risk for getting and giving HIV through oral sex, too.
Using a latex barrier is your best chance of avoiding most STDs during oral sex. A condom can be used on a penis to protect a guy and his partner from STDs.
A dental dam—a thin sheet of latex—can be used for oral sex on a vagina or anus. You can get dental dams at a clinic. Sexual partners can also cut a condom lengthwise to create a sheet that works like a dental dam to use as a barrier.
