Sex can be an enjoyable, life-enhancing experience. Abstinence is the only sure way to prevent pregnancy and STDs.
Some sexual activities are much safer than others, though.
Vaginal , anal or oral sex can spread any viruses, bacteria and parasites present in bodily fluids. Some activities may cause tiny tears in genital or rectal tissues. This allows bacteria and other organisms to penetrate the skin and cause infections. Pregnancy is a risk, too, with unprotected intercourse. Some types of HPV increase a woman's risk of cervical cancer or precancerous changes of the cervix , called cervical dysplasia .
