Think they could be sleeping around? Watch out! STDs spread fast that way.
Protecting yourself is one of the most important things you can do for yourself in a relationship. Understandably, it can be very hurtful to learn that your partner has given you an STD, especially if you didn’t know your partner was having sex with someone else. Sometimes you can have a new relationship and the person you are with doesn’t know he or she has an STD. This is why, when two people are thinking about having sex with each other, they should get tested before they have sex.
If you are having oral sex with a guy, or vaginal or anal sex, you should always protect yourself by using condoms. If you are having oral sex with a girl, you should use a dental dam.
You should always talk with your partner about STD testing and make sure you both get tested before you have sex.
