What is 'safe sex'?

Safe sex means sexual activities which you can do even if one person is infected with HIV, and they definitely won't pass it on to the other person. Loads of activities are completely safe. You can kiss, cuddle, massage and rub each other's bodies. But if you have any cuts or sores on your skin, make sure they are covered with plasters (band-aids). Nothing you do on your own can cause you to get HIV - you can't infect yourself by masturbation.
