Key Takeaways

Period sex is safe — menstrual blood is not dirty, harmful, or a health risk to either partner
Many people report heightened pleasure during menstruation due to increased blood flow and hormonal shifts
Orgasms during periods can help relieve cramps through uterine muscle relaxation and endorphin release
Practical preparations (dark towels, shower option) make cleanup simple
Communication and mutual comfort are the only requirements — if both partners want it, there is no medical reason not to

Period sex occupies an odd cultural space: it is extremely common (studies suggest over 70% of sexually active people have had it), yet it remains surrounded by unnecessary stigma, squeamishness, and misinformation. The primary objection — that it is "dirty" or unhygienic — reflects cultural discomfort with menstruation itself rather than any legitimate health concern.

Menstrual blood is not toxic. It is not waste in the way that urine is waste. It is a combination of blood, uterine tissue, cervical mucus, and vaginal secretions. It carries no additional health risk beyond what is present during non-menstrual intimacy. With basic precautions, period sex can be comfortable, pleasurable, and — for many people — better than non-period intimacy.

Is It Safe?

Yes. Medically, there is no reason to avoid intimacy during menstruation. However, two points deserve attention:

STI transmission risk is slightly higher. Blood-to-blood or blood-to-mucous-membrane contact can facilitate transmission of blood-borne infections. If either partner's STI status is uncertain, barrier methods (condoms) are particularly important during period sex.
Pregnancy is still possible. While less likely during menstruation, sperm can survive in the reproductive tract for up to five days. If you ovulate shortly after your period ends, conception from period sex is possible. Contraception should continue as normal.

Why It Can Feel Better

Increased Blood Flow

During menstruation, blood flow to the pelvic region is already elevated. This increased circulation means that genital tissues are already partially engorged, which can make them more sensitive to touch and stimulation. Some people report that arousal comes faster and sensations are more intense during their period.

Natural Lubrication

Menstrual blood acts as a natural lubricant. For people who sometimes experience insufficient lubrication, period sex can feel smoother and more comfortable. This is purely a physiological bonus — menstrual fluid reduces friction and enhances sensation.

Hormonal Shifts

Oestrogen and progesterone levels are at their lowest during menstruation, which can paradoxically increase desire in some people. The hormonal profile during menstruation is different from the rest of the cycle, and some people find that this translates to a shift in how arousal feels — sometimes more primal, less cerebral.

Cramp Relief

Orgasm causes the uterus to contract and then relax, which can relieve menstrual cramps. Additionally, the endorphin release during orgasm acts as a natural painkiller. Multiple studies have found that people who have orgasms during menstruation report reduced cramping and improved mood. It is a genuinely therapeutic effect.

Expert Insight Gynaecologists note that there is no medical reason to abstain from any form of intimacy during menstruation, including penetrative sex, oral sex, and manual stimulation. The choice is entirely about personal comfort — yours and your partner's. If the concern is purely about mess, practical preparations easily address that. If the concern is about health, the evidence is clear: it is safe.

Practical Tips

Dark towel. Place a dark-coloured towel beneath you. This single step addresses 90% of cleanup concerns.
Shower sex. If mess is a concern, the shower is a natural solution — running water eliminates cleanup entirely.
Lighter flow days. If you are easing into period sex, start on days 1-2 (before heavy flow) or days 4-5 (as flow lightens). Build comfort gradually.
Menstrual discs. Unlike tampons (which should be removed before penetration), menstrual discs sit higher in the vaginal canal and can be worn during intercourse, reducing mess significantly.
Keep wipes nearby. Wet wipes or a warm washcloth within reach makes post-intimacy cleanup quick and stress-free.
Position matters. Missionary with the menstruating partner on their back tends to produce less mess due to gravity. Side-lying positions are also practical.

Having the Conversation

Period sex requires communication — full stop. Neither partner should feel pressured into it, and neither should feel ashamed for wanting or not wanting it.

If you want it: "I am on my period but I am really in the mood. How do you feel about it?"
If you are unsure: "I have never tried period sex but I am curious. Would you be open to it?"
If you do not want it: "I am not comfortable with it tonight, but I would love to connect in other ways." Alternatives include external stimulation, mutual massage, or simply being close.

Period Sex Safe Guide: Your Questions Answered

Can period sex shorten your period?

Potentially. The uterine contractions during orgasm can help expel menstrual fluid faster, which some people report shortens the overall duration of their period. The effect is modest but documented.

Is oral sex during periods safe?

Yes, with the same STI precautions as any other time. A dental dam can be used as a barrier. Focus on external (clitoral) stimulation if blood contact is a concern. Many couples are comfortable with it; others are not. Both responses are valid.

Should I remove my tampon before sex?

Yes, absolutely. Tampons must be removed before penetrative sex. A forgotten tampon pushed further into the vaginal canal can be uncomfortable and increase infection risk. Remove it, check that it is fully removed, and proceed. Menstrual discs are the only internal menstrual product designed to be worn during intercourse.

Will period sex cause an infection?

No. Period sex does not cause infection. The vaginal environment is slightly more alkaline during menstruation (due to the blood), which theoretically could make infections like BV slightly more likely, but this risk is minimal and managed by standard hygiene practices. Urinating after intercourse and gentle external washing are sufficient.

My partner is uncomfortable with period sex. How do I handle this?

Respect their boundary without internalising it as rejection. Their discomfort is about their own comfort zone, not about you or your body. You can offer information to address misconceptions, but ultimately, mutual enthusiasm is essential. Explore other forms of intimacy during your period — there are many ways to be close that do not require penetration.
