I have read over the internet that HIV can be transmitted through oral sex in such a way whereby the HIV virus theoretically could gain entry from the mouth of the infected partner(the one giving oral sex)to the opening on the tip of the penis even though there is no open cut or lesion on the penis.If you receive oral sex, however, you mainly expose yourself to saliva, which has negligible concentrations of HIV(this statement is quoted from Brown University health education).Other than HIV,you can also contract other STDs like herpes,gonorrhea and syphilis from unprotected oral sex(both fellatio and cunnilingus).But I have gone thru medhelp forum and most of the time you will tell us that you will never contract HIV from oral sex.So who is more accurate?Can we contract HIV when the saliva of an infected HIV positive woman enters the tip of our penis?Pls advise.Thank you!
