Like most avant-garde fetishes, the rainbow kiss evolved from a more mainstream sex act – think of the classic 69 position, but with a ‘colourful’ twist. What makes the rainbow kiss sexual in a very polarising way?

“You’ve heard the term ‘running the red light?’ This is a level up from that,” writes Dr Wendasha Jenkins Hall; founder of The Sensible Sexpert.

If you’ve got no idea what is a rainbow kiss definition then Dr Hall is referring to the act of performing oral sex on a female partner, in the 69 position, while they’re on their period. And while ‘period sex’ is not a foreign concept to many, here’s the kicker when it comes to the cloudy rainbow kiss part…

“Once both partners have ejaculated in each other’s mouths, the couple kisses, mixing menstrual blood with semen in the process, thus the ~rainbow~ part of the rainbow kiss. And voilà!” write Cosmopolitan.

Well, there you have the rainbow kiss def finally. A rainbow kiss essentially involves swapping menstrual blood and semen via lip-to-lip contact. To put things lightly, the special rainbow kiss embrace is not everybody’s cup of tea.

But according to Dr Hall, the rainbow kiss is only one of many sex acts people with bodily fluid fetishes perform. And it’s not a new concept, either. So why has the phrase experienced a viral resurgence via  TikTok in recent months? Just check out a rainbow kiss TikTok which is one of many below.

Since late last year, people have been chronicling their rainbow kiss TikTok journeys, revealing what they thought a rainbow kiss means versus what a rainbow kiss actually is.

“I thought it was bout to be sum fruity bro…” wrote one user in the caption of a rainbow kiss TikTok posted in 2021.

Look, we’re not here to rainbow kiss kink shame. If french kissing your beau is getting a little boring and you want to mix things up with a rainbow kiss then more power to you. However, there are additional health risks associated with the rainbow kiss, so it’s important to prioritise safety if you’re planning on giving someone a rainbow kiss anytime soon.

“Semen and period blood can carry lots of different infectious particles, such as HIV, syphilis, and hepatitis,” warns Dr Heather Irobunda, a licensed ob-gyn about the rainbow kiss.“If you are unsure of your partner’s STD status, you should not be sharing rainbow kisses. But if all partners are actively testing and they understand the boundaries and offer their consent, then it’s typically safe.”

Of course, like every sex act, consent is key. As Dr Hall explains, the rainbow kiss is “typically done among partners who take these safety precautions—they’re not done with a person on the street or a person on an app. It’s not a one-night stand kind of thing.”

She continues, “there has to be some consent around what’s going on, there has to be safe words, limitations, and hard boundaries because of the disease and illness factors.”
