If you’ve never heard about “rainbow kiss,” then you might probably think of it as something wholesomely romantic. Some even assume that it’s related to queer relationships. However, after reading this guide, you’ll definitely perceive this term in a different light.
There’s a recent trend on TikTok wherein people would record their reactions to searching and reading the meaning of “rainbow kiss” on google. Most of the people who joined the trend were disgusted, confused, or amused.
There are also some videos of peeps warning other people not to search for the term and that not knowing it is for their own good. However, it’s our human nature to be curious, so most people who’ve watched these videos went on searching for it— most of them end up with the same reactions as the tiktokers.
As you’ve read about this trend, you’re probably itching to know what a rainbow kiss is. Don’t worry, though, as we’ll share the basics in this guide. We’ll discuss what rainbow kiss is, how to safely do it with your partner, and other essential info when trying out this sexual activity.
What is the Rainbow Kiss?
A rainbow kiss is an unconventional sexual activity between straight couples wherein menstrual blood and semen are mixed during a kiss. They would collect each other’s blood and semen as they performed oral sex with each other. After that, they would go for a kiss that would mix these fluids.
We get what you’re thinking— this is gross and weird. However, some people enjoy involving bodily fluids in their sexcapades. People who have semen and menstrual blood fetishes may see the rainbow kiss as a highly arousing activity.
What’s the Origin of the Rainbow Kiss?
This whole mixing-menstrual-blood-with-semen activity originated through the urban dictionary, a crowdsourced online dictionary for slang terms and phrases.
It was posted back on March 13, 2003, by username Duncan and refers to rainbow kiss as “Indeed, the term refers to performing cunnilingus on a menstruating female, often followed by orally swapping semen and blood/other secretions. NOTHING to do with homosexuals.”
Is it Safe to Perform a Rainbow Kiss?
If you’re interested in trying this sex act, keep in mind that doing a rainbow kiss is extremely risky.
Several doctors have also shared their thoughts about this activity, asking people to not do it and that couples who would try it may end up with an infection.
We get that some people get off with the idea of tasting bodily fluids and some people will do anything for the sake of the sexual thrill. But you shouldn’t do unconventional sex acts at the expense of your own health.
If you’re really up for the rainbow kiss, you and your partner must take blood and STI tests first! Once it’s confirmed that you’re both cleared from infections, then that’s the time that you can try this sexual act.
It doesn’t matter if you’ve been in a monogamous relationship with your partner for years. Some sexually transmitted infections don’t have symptoms, and if you’re both never got tested before, then you’re not actually sure if your partner has underlying infections or not. Your health and safety should be your number one priority.
And for those who are planning to try a rainbow kiss during a hookup, stop right there! It’s not safe. Don’t do it unless comprehensive medical tests are done beforehand.
How to Perform a Rainbow Kiss
If you and your partner are really into the whole blood and semen thing and want to try this sex act, minimize the risk by following these steps.
1You and your partner must get tested before the deed.
We know we’ve mentioned it in the previous section, but we can’t emphasize this enough. Make sure that you and your partner get tested a few days before the deed. No buts, no ifs.
Don’t get swayed by your partner’s “I’m clean for sure…” statements. The only way to know your partner’s sexual health status is by a series of STI tests.
You and your partner must consult a sexual health professional to get the list of the necessary screenings that you should take. This may include HIV, syphilis, and hepatitis B tests. Once you’re both done with the necessary tests and cleared from sexually transmitted infections and other infectious particles, you then proceed on to the next step.
2Make the necessary preparations.
After finding each other’s sexual health status, you’ll have to schedule an appropriate day to try the rainbow kiss. Since you or your partner have to collect enough period blood for the kiss, doing the deed on your own or your partner’s heaviest menstrual cycle seems to be the ideal time.
While waiting for that, you or your partner can consume foods that’ll provide better semen consistency and can also make the taste of the cum a lot tolerable, such as the following:
On the day of the activity, make sure to brush your teeth or floss at least two hours before the rainbow kiss. Don’t do it right before the deed, as bacteria and viruses can enter your bloodstream through tiny cuts on your gums caused by flossing and brushing. If you want to freshen up your mouth, just gargle some mouthwash beforehand.
3Get into a 69 or 69-related position.
Start the activity by getting into a 69 position. The man should be lying on their back, while the woman should be on top of him; your face should be right next to your partner’s genitals.
If you’re uncomfortable with the classic 69, there are other 69 variations that you can try when doing a rainbow kiss; more of that in the next section.
4Collect the bodily fluids while performing oral sex on each other.
After getting to the position, now’s the time for giving and receiving oral sex. Simply use your mouth and tongue to lick and suck your partner’s penis or vulva.
For the guy, make sure to collect period blood while licking their vaginal opening. If you’re up for some challenge and aren’t squeamish for their blood, you can try sucking it from the vagina.
As for the woman in this sex act, just do the usual blowjob techniques. Once your partner is cumming, keep the tip of your partner’s penis in your mouth and let the semen shoot into it. Don’t swallow.
5Kiss each other torridly, mixing the cum and period blood in the process.
Once the male partner has reached the orgasm, get off from the 69 positions and go for an intimate position, like missionary or lotus position. Kiss passionately, mixing the collected fluids from each other’s mouth, forming the rainbow kiss at the end.
Bodily fluids taste differently. You may either find it tolerable or disgusting. Just make sure that there are a waste bin, tissues, or plastic bags within reach in case you or your partner end up vomiting or spitting in the middle of the deed.
Don’t forget to spit out the bodily fluids at the end of the deed and gargle some mouthwash before proceeding with other sex acts.
Sex Positions for the Rainbow Kiss
Now that you’ve learned the steps on doing the rainbow kiss, some of you are no longer interested in trying it, while others might be extra pumped for the deed. Here are some suggested variations of the 69 position that you can try when doing the rainbow kiss.
If you want a more comfortable version of the 69 position, we highly recommend this one. As the name implies, you’ll be 69-ing, but sideways. Just lie on the side, facing each other’s genitals. Open your legs wide and start giving and receiving oral sex.
If you’re both on the opposite end of the spectrum and want a harder 69 variation, consider doing this position when going for a rainbow kiss.
For this one, the man will be sitting down, subtly putting their back on a reclining position. The woman will then stand up with their crotch right above their partner’s face. She will then have to squat and bend over.
Another advantage of this position is that the menstrual blood will flow quicker in this 69 variation. This means that the man will be able to collect more period blood for the rainbow kiss.
3Wine & Dine & 69
Here’s another sex position that lets the guy collect menstrual blood more easily. For the Wine & Dine & 69 position, the man should lie on their back. Meanwhile, the woman should stand on the edge of the bed/dining table, with her crotch next to her partner’s face.
Once positioned, the woman should bend over to perform oral sex, while the guy will place his head in the middle of his partner’s thighs to perform cunnilingus.
If the rainbow kiss is not enough of a challenge and you want to amp things up, consider going for the chair 69 position. It’s one of the most difficult 69 variations, as you’ll need to keep the balance throughout the deed.
To do this position, start by looking for a sturdy armless chair. After that, the woman should lie on her back across the chair. She will then spread her legs apart, placing her feet on the floor and her head hanging on the opposite edge of the chair.
Once she’s positioned, the man will then bend over his partner’s body in the opposite direction, his crotch facing near the woman’s face. He should then hold the upper part of this body over his partner’s torso. Once everything’s set, they can then perform oral sex on each other.
Another challenging 69 variation on this list is the Upside Down position. This works well for a flexible woman, so if you or your female partner have back issues, we don’t recommend trying this one.
To do this position, the man should sit down, slightly bending his knees and spreading his knees apart. After that, the woman should stand, facing the same direction; her partner should be facing her butt.
Then, the woman should fully lean forward for her head to be between her partner’s thighs. Her hands should be near her partner’s knees, and her feet must be from the outside of the man’s hips. Once everything’s positioned, they can then start having oral sex.
