I can do it, but it doesn't affect me. I just want to tell the doctor about the situation. In fact, HIV itself is not terrible, but I want to stay away from high-risk behaviors when necessary. I was young and ignorant before and had unprotected sex many times. I once saw an explanation about saliva, fluid, collection and utensils on the Internet. It says here that saliva can be used to check for AIDS. Later, I found a box on the Internet and tried it.
