Thank you for asking follow up question.
I am happy to help you.
Although oral sex is a relatively low-risk activity, particularly when compared to vaginal or anal sex, it is possible to transmit HIV through oral sex. The risk of HIV transmission from an infected partner through oral sex is much less than the risk of HIV transmission from anal or vaginal sex.The risk of HIV transmission increases if you have cuts or sores in your mouth.
Practiaclly it is said that untill someone has significant amounts of blood in his mouth, such as from dental surgery,oral sex is unlikely to expose the receptive partner to HIV. The risk is more when one has bleeding gums or a cut or ulcer inside their "mouth",they risk HIV entering their bloodstream through infected fluid.
It is uncommon & relatively rare to get HIV infection this way.
So botXXXXX XXXXXne is that although your sore cracked lips, slightly increases the chances of transmission of HIV ,but still it is very low that is the transmission of HIV this way is very low,but again-you need to get it tested at an STD clinic.
