On a way back from trip, my friend had protected sex multiple times in one of the massage parlours with multiple partners. This includes kissing, b2b massage and protected sex. However he made sure to use condom before inserting. Also he made sure to use Azthromycin 500 and Cobadex CZS (Multi
Vitamin) every time he had sex(I,e Within 24 hours) It's been 3 days he has returned from trip and there are no signs of infections. Should he be worried with any sorts of infections?
