I also know cases of guys who had sex with female bargirls in Thailand and got HIV from them because they didn't use a condom. Even instances of guys who used a condom and still somehow got HIV.
Old SiFi stories from 1980's by old farangs !. No condoms , yeah right !.
Every GoGo bar girls & hostesses must be ID/Medically registered !. Freelancers too.
Just look how Thailand control spread of China virus (only 58 dead) & is in process of re-opening !.
Now no entry into Thailand without medical insurance & covid -19 certificate !.
