You can also give your partner an infection.
Vaginal sex – this is when a penis goes in a vagina
Anal sex – this is when a penis goes in the anus
Oral sex – when you lick or suck a penis or vagina
Touching – when you touch another person’s penis or vagina
Others are with you all your life.
If you are having sex and don’t want to catch an infection you need to use a condom.
Many infections don’t have any symptoms. This means you don’t always know if you have one.
