If an adult hiv -ve man sucks a hiv +ve woman's breasts can he get infected by hiv even if he's using a condom during sex?

Yes: It's transmitted by body fluids, and there may be breast secretions.

Possible: Wearing a condom will not afford any protection from sucking on a breast. If the breast is producing milk and any blood is present in the milk, the risk of contacting HIV is increased.

No: There is HIV present in breast milk but adult transmission through breast milk is not documented.Breast milk from an hiv-positive woman can transmit the virus while breastfeeding infants. There are no recorded cases of HIV transmission via breast milk in adults. However, there is at least a very small negligible but theoretical risk.
