The risk of contracting a sexually transmitted infection from unprotected oral sex is generally lower compared to other forms of sexual activity, such as vaginal or anal sex. However, it is still possible to transmit or receive certain STIs through oral sex, though the likelihood varies depending on several factors:
1. Presence of an STI: The risk increases if either partner already has an active STI, such as herpes, gonorrhea, syphilis, or chlamydia. These infections can be transmitted through oral-genital contact.
2. Open sores or cuts: If there are any open wounds, sores, or cuts in the mouth or genital area, the likelihood of transmission may increase.
3. Ejaculation: If the partner ejaculates in the mouth, there is a higher risk of transmission for certain STIs, including gonorrhea or chlamydia.
4. Pre-existing conditions: People with weakened immune systems, such as those living with HIV, may have an increased risk of contracting or transmitting STIs.
It's essential to remember that condoms can help reduce the risk of STIs during oral sex.
