safe sex
sexual activity in which the exchange of bodily fluids is inhibited as much as possible to help reduce the risk of unwanted pregnancy or of contracting sexually transmitted diseases. Precautions may include avoidance of high-risk sexual behaviors, careful selection of one’s partners, and the use of preventive barriers (e.g., condoms, dental dams). The practice is also called safer sex in recognition that 100% safety is not possible with, for example, condoms.
