Someone can get an STI through sex and through other ways of transmission.
Transmission through sex
- Through vaginal sex, anal sex or oral sex with someone who has an STI, without using a condom.
- By sharing sex toys without using a condom. For instance: dildo, vibrator. Always use a new condom when a different person uses the sex toy.
- Through contact with blisters (herpes), sores (syphilis) or genital warts on someone’s skin.
Transmission in other ways
Talking to your partner and the doctor
Talk to your partner about it and encourage him/her to go to a doctor. You protect yourself this way too. If your partner is not treated, you can become infected again if you have sex without a condom.
If you have recently had sex with another person, warn him or her too. Then this person can also get tested and treated.
