No, it is not possible to get HIV from kissing.
HIV is only spread when the following bodily fluids come into direct contact with your bloodstream or mucous membranes:
- Breast milk.
- Vaginal fluids.
- Rectal fluids.
- Pre-seminal fluids.
In the past, people thought it was possible to transmit HIV if both you and your partner had open sores or cuts in your mouth and your partner was HIV positive. However, this scenario has been debunked. Since it is not possible to spread HIV through saliva there is absolutely nothing to worry about.
