What is the rainbow kiss?

The Rainbow Kiss is a purported sexual act involving blood exchange. It allegedly involves one partner engaging in oral sex on the other until they bleed, followed by the other partner performing oral sex on the first, mixing the blood in their mouths, and then kissing.

It is important to emphasize that the Rainbow Kiss is widely considered to be an urban legend. There's no credible evidence of it being a common or even practiced act.

More importantly, engaging in any sexual activity involving blood exchange poses significant health risks, including the transmission of sexually transmitted infections (STIs) like HIV, hepatitis B, and hepatitis C.
