Rubber condoms are thin sheaths made from latex or synthetic rubber designed to prevent pregnancy and reduce the risk of sexually transmitted infections (STIs). They are typically worn over the penis during sexual intercourse and act as a barrier to keep sperm from entering the vagina. These condoms are widely available in various sizes, textures, and flavors, catering to different preferences. Proper use and storage are essential for effectiveness, as exposure to heat or sharp objects can damage them. Always check the expiration date and ensure the packaging is intact before use to ensure safety and reliability.
