Do all condoms prevent aids equally?

NO !!! Read the packages carefully. The "natural" condoms usually do not protect against sexually transmitted diseases (std's) including hiv/aids, hepatitis, herpes, etc. The labeling will often say natural, lambskin, ultra sensitive, etc. Sperm are big, but bacteria and viruses are small: get the condom that protects you from both. Also remember, no condom is 100% effective. Be careful out there!
