For the safety of comrades, we should carry out safe procedures for making friends: 1. Make friends first, observe their conduct; 2. Check and test; 3. Make love at last; 4. Ensure the purity of two people and refuse multiple people.
Before both parties go to a regular hospital for examination and testing, they should avoid having sex. If it happens, they should use condoms from mouth to anus and check them from time to time to prevent being cheated and getting sick.
