“Performing a rainbow kiss does come with its risks as both menstrual blood and semen can potentially carry infectious particles including syphilis, hepatitis, and HIV,” says Dyachenko. “If you're not fully aware of your partner’s sexual history and whether or not they have any STIs, I'd advise against participating in rainbow kisses.” STIs are incredibly common and talking about safer sex should be NBD. So please, for the love of all things sexy, get tested and have the STI talk.
Let’s say all the stars, talks, and safety align. There are a lot of positives that could come from a rainbow kiss. If you are menstruating, research suggests that sex alleviates some symptoms of PMS. Also, there’s increased blood flow to the genitals, thus the potential for increased sensitivity. Orgasms release a rush of feel-good brain chemicals, including dopamine and oxytocin, which can ease cramps. Think of it as an all-natural period pain reliever.
And as much as I evangelize the liberal use of lube, menstrual blood acts as a mighty fine natural lubrication. (Some vulva-owners may still experience vagina dryness even while menstruating, though.)

There’s more good news. Having sex during your period can be a pleasurable source of stress relief and a way to bond with your partner. Signal the period sex anthem sung by “Crazy Ex-Girlfriend’s” writer, star, and co-creator, Rachel Bloom. The catchy anthem includes gems like, “Put down a towel and party ‘till it’s dry with some period sex,” and, “Think of it as Mother Nature’s juice cleanse.”
The Bottom Line
Oral sex is a highly intimate act, and swapping fluids orally can increase sexual connectedness. Rainbow kisses may not be for everyone, and that’s OK. When it comes to sex acts, it tilts to the high-risk end of the spectrum. Whether you fantasize about the idea of blood play or make it a menstrual reality, consider the rainbow kiss simply one more source of pleasure in your sex play toolkit.
