Hello
Read this carefully , you will get answer.
Although HIV can be isolated typically in low titers from saliva of a small proportion of infected individuals , there is no convincing evidence that saliva can transmit HIV infection , either through KISSING or other exposures, such as occupationally to any one.
Although virus can be identified, if not isolated , from virtually any body fluid , there is no evidence that HIV transmission can occurs as a result of exposure to teats, sweats & urine.
Gum bleeding is not specific in this case because saliva has property as anti viral agent.
Licking of nipples and kissing is safe and you should not worry .
Hope this will help you.
Good luck.

Thank you for query.The chances of transmission of HIV by sexual route is 1/ 200 to 1/2000 even if the partner is HIV infected.the chance of transmission of HIV by oral route is very very rare.the chance even if she is HIV positive by oral is rare as virus does not survive through the GI tract.Only if ulcers or abrasions are present in the mouth there are very rare minor possibilities.Even the nipple sucking also does not transmit HIV.You can allay fear of HIV.But there are diseases like herpes which can be transmitted by kiss and touch.You can get back for any clarifications with details.Dr Bharatesh D Basti Dermatologist and venereologist.
