Many people question whether oral sex is really sex. That depends on how you define sex, but one thing is clear—oral sex isn't inherently safe sex. Sexually transmitted infections STIs are definitely a risk, at least if you don't take proper precautions. Oral sex is a relatively low-risk activity for HIV transmission, particularly when compared to vaginal or anal sex. The risk of HIV is largely limited to the person performing oral sex.

Oral sex STD risk charts: Safety and prevention
Sexually transmitted diseases STDs are increasingly common and service providers working in STD prevention are often asked about the chance of getting an STD from a one-time heterosexual sexual encounter. What do studies tell us about how commonly an STD results from one-time sex? How can we interpret the results? Males and females are equally likely to contract most sexually transmitted infections, but females are at higher risk of acquiring some of them. It is not easy for researchers to calculate the risk of contracting HIV through sex between heterosexual couples.
STD Risk and Oral Sex - CDC Fact Sheet

The penis and testicles and the vagina and area around the vagina are also called the genitals or genital area. Oral sex is commonly practiced by sexually-active adults. Many STDs, as well as other infections, can be spread through oral sex. Anyone exposed to an infected partner can get an STD in the mouth, throat, genitals, or rectum.
Back to Sexual health. Oral sex is the stimulation of the genitals using the mouth and tongue. You can catch an STI if you have just one sexual partner. However, the more partners you have, the greater the risk of catching an infection.
