Unprotected Sexual Intercourse

You’re more likely to get HIV or another STD when you have more than one sex partner, or many sex partners during your lifetime. That’s because more people mean more chances that one or more of them will have HIV or an infection. Ever heard the saying that when you have sex with someone, you’re having sex with everyone they’ve ever had sex with?The lowest risk, unless you’re celibate, is being in a relationship where both people are exclusive. Life is complicated, though, and that may not be realistic or what you both want. Or you may not know that your partner has been seeing someone else. So it’s a good idea to get tested for STDs together, and share the results with one another.
