Name one method to help prevent HIV transmission during sexual activity.

Using condoms is one of the most effective methods to help prevent HIV transmission during sexual activity. Condoms create a physical barrier that prevents the exchange of bodily fluids, which is the primary route of HIV transmission. When used consistently and correctly, condoms significantly reduce the risk of spreading HIV and other sexually transmitted infections (STIs).

In addition to their effectiveness in disease prevention, condoms are widely accessible and can be utilized in various forms of sexual activity. This makes them a critical tool in sexual health education and prevention strategies.

Other methods mentioned may contribute to overall sexual health, such as abstaining from sexual activity (which would entirely eliminate the risk of transmission) or limiting the number of sexual partners (which can reduce the risk of exposure). However, these strategies do not provide a direct barrier like condoms do. Oral contraceptives are primarily designed to prevent pregnancy and do not offer any protection against HIV or other STIs.
