Yes, it’s possible to have an STI without having had penetrative sex. Several STIs can be transmitted through oral sex, skin-to-skin contact, sharing drinks or during birth. So “virgin” — if defined as never having had vaginal or anal sex — doesn’t guarantee you haven’t been exposed to STIs.
Here’s a practical explanation.

Common Scenarios
Oral sex
Oral sex carries genuine STI risk for several infections. Many people don’t count this as “sex” but it can transmit chlamydia, gonorrhoea, herpes, syphilis and HPV.
Genital skin contact
Rubbing or touching between genitals without penetration can transmit herpes, HPV and pubic lice.
Kissing
HSV-1 (oral herpes) is commonly acquired through kissing, often in childhood.
Sharing needles
Injecting drugs or sharing equipment (including for tattoos done unsafely) can transmit HIV and hepatitis without any sexual contact.
Born with infection
Babies can acquire STIs from their mother during pregnancy, birth or breastfeeding.
Why This Matters
- You can have an STI even if you consider yourself a virgin
- Testing isn’t just for people who have penetrative sex
- Safer oral sex is as important as safer penetrative sex
- Vaccinations (HPV, hepatitis B) protect even those who haven’t had penetrative sex
Protecting Yourself
- Get the HPV vaccine (routine in UK schools)
- Get hepatitis B vaccine if at risk
- Use dental dams or condoms for oral sex
- Avoid sharing personal items like razors
- Test if you have symptoms regardless of “virgin” status
