What is rainbow kisses?

A "rainbow kiss" is a purported sex act that is widely considered to be an urban legend or hoax.

It allegedly involves one partner bleeding from the mouth and another partner bleeding from the anus, and then the two partners kissing, mixing the blood in their mouths. The name supposedly comes from the resulting "rainbow" effect.

There is no credible evidence to suggest this is a real or safe practice. It carries significant health risks due to the transmission of bloodborne diseases such as HIV, hepatitis, and other infections. Medical professionals strongly advise against any activity involving the exchange of blood.

The rainbow kiss is primarily encountered in online forums and discussions related to extreme or unconventional sexual practices. Due to the extreme risk of disease transmission, it is important to consider that this act may only be a fantasy or form of shock content.
