Here's a text conversation I recently had with a new sexual partner.
Me: I have my period. How do you feel about getting together while that's going on?
Him: Well, I thought having sex during your period hurt more?
Me: What?! Where did you hear that?
Him: LOL okay, I'm shutting up, please tell the person without the uterus about period sex…
And reader, believe me, I absolutely did tell the person without the uterus about period sex.
Period sex can be messy, yes. Let's get that out of the way. Someone is experiencing a menstrual period, which means their body is doing exactly what it's supposed to do, shedding a uterine lining that took a month to build. There will be blood. There might be a towel involved. None of that makes it unsafe, unhygienic, or something to whisper about, and yet somehow we're still having this conversation like it's scandalous. So let's talk about why.
The taboo around periods didn't appear out of nowhere, and it definitely didn't appear recently. Ancient writers were already spreading wild claims about menstrual blood thousands of years ago. The Roman writer Pliny the Elder claimed that menstrual blood could sour wine, kill crops, and drive dogs mad. Religious texts across several traditions labelled menstruating people “unclean” and restricted where they could go or what they could touch. Some of those restrictions still exist today. Menstruating people are barred from Eastern Orthodox communion, and in Nepal the practice of chhaupadi, which exiles menstruating women to huts away from their homes, was only officially banned in 2018, despite still causing deaths in rural areas since.
Even the language we use reflects how much we've been trained to avoid the word itself. Researchers have counted well over a hundred euphemisms for periods across cultures, from “Aunt Flo” to “strawberry week” in Austria to “I'm with Chico” in Brazil. Every one of those phrases exists to help someone talk around menstruation instead of naming it directly, and linguists studying the topic argue that this kind of code-switching quietly reinforces the idea that periods are something to hide rather than a completely normal bodily function.
Once you stack a few thousand years of that messaging on top of each other, it's not surprising that period sex still gets treated as the taboo within the taboo. If people struggle to say the word period out loud, asking them to also be comfortable having sex during one is a bigger leap than it should be.
Here's where things get more interesting than the stigma would suggest. Orgasms cause the muscles of the uterus to contract and then release, which is the same basic mechanism behind menstrual cramps in the first place. That release can genuinely take the edge off period pain. Sexual health researchers point to this as one of the more reliable benefits of period sex, alongside the endorphin release that comes with any orgasm, which helps counter pain and low mood more generally.
There's more. Menstrual blood acts as a natural lubricant, which some people find makes penetrative sex more comfortable rather than less. Hormone shifts around menstruation can also increase libido for some people, meaning the timing that feels least convenient on paper might actually line up with when they're most in the mood. Some people also report that orgasms during their period seem to shorten it slightly, since uterine contractions may help move blood and tissue along faster, though this particular claim is mostly anecdotal rather than something researchers have confirmed with hard data.
If mess is what's holding you back, there are a few straightforward ways to work around it. Laying down a towel or a waterproof sex blanket takes most of the anxiety out of the equation. Showering together turns the whole thing into part of the experience rather than an obstacle. And if penetration feels like too much on a heavier day, there's still plenty on the table. External stimulation, mutual masturbation, and oral sex are all just as available during a period as any other time of the month, and lighter flow days tend to involve far less blood than people expect going in.
One thing worth being clear about: You cannot have penetrative vaginal sex with a tampon or menstrual cup still inside. It's a common enough question that it's worth answering directly. Beyond simply not working, it's genuinely risky. A tampon can get pushed further up and become difficult or even impossible to remove without medical help, and the same goes for a cup that gets dislodged. If you want to avoid dealing with blood during oral sex specifically, leaving a tampon or cup in for that is fine, since nothing is being pushed further in. Just remember to take it out before anything penetrative happens.
Ask around and you'll notice something odd: Almost nobody is lukewarm about period sex. People tend to be enthusiastically into it or completely opposed, without much middle ground. Part of that probably comes down to how deeply the taboo runs. When something has been coded as off-limits for this long, reactions tend to be strong in one direction or the other rather than casual. The people who've pushed past the initial discomfort often become genuine advocates for it, while the people who haven't tend to hold firm on avoiding it altogether. Neither reaction is wrong. What actually matters is that the decision gets made with accurate information rather than outdated myths about pain, hygiene, or risk.
Anyway, here's how that text conversation with my new sexual partner ended.
Me: So I repeat, how do you feel about getting together while I have my period?
Him: I don't mind period sex if you're good with it.
My work here is done… For this month, at least!
Yes. Menstrual blood is a normal bodily fluid, and period sex carries no extra risk beyond the usual considerations for any sexual activity. The main thing to be aware of is a slightly higher chance of STI transmission, since STIs can be carried through blood, so barrier protection is still worth using if that's relevant to you.
No, not for penetrative vaginal sex. A tampon or cup can get pushed further inside and become difficult to remove, which can lead to discomfort or even require medical help to sort out. It's fine to leave one in for oral sex, since nothing is being pushed further in, but always remove it before anything penetrative.
It can. Orgasms cause the uterine muscles to contract and then release, which is the same mechanism behind menstrual cramps, so that release can genuinely ease the pain. Orgasms also trigger a release of endorphins, which help with pain and mood more broadly, regardless of where they come from.

What is compersion?
Compersion is often called the opposite of jealousy. Here's where the word came from, how it connects to polyamory, and what it feels like.
