Oral sex is generally low risk, with few side effects.
We do see some STIs passed with oral sex, including: HPV, herpes, chlamydia, gonorrhea, and syphilis.
Has your boyfriend received oral sex from anyone else before? Has he had penetrative sex with anyone else before?
- If not, then he can’t have any STIs to pass to you.
- If yes, then it’s possible for your partner to have an STI that is passed to you through oral sex.
Talk with your boyfriend. If he has had other partners in the past, it might be good to go for an STI test.
Also, listen to your own feelings and thoughts when engaging in sex. If you don’t feel comfortable doing something, you can always say “no” or “not now”.
