One question, why my country's medic keep saying for those who have sex with sex worker before no matter have used condom or not, they still better to have a test every half year or every year?
As I think it is 100% safe then those medic shouldn't waste money for those zero risk people.
And meanwhile, I want to know is it the skin on penis can protect us against the HIV too? So which part of penis must be covered by the condom to protect us against HIV?
Thank you.
