My brother who is around 21 years old had sex with a sex worker and he didnt touched her, he had an intercourse from the back only but he told me that after ejaculating he kept doing it for almost 10-15 seconds but after that he checked the condom and the condom was not broken or leaked so is there a chance of
std and sti as he did it with protection, he is very worried. Is there any chance of
hiv or something like that
