Having sex with a tampon in won’t cause a medical emergency in most cases, but it can lead to real discomfort, minor tissue injury, and a tampon that’s difficult to retrieve afterward. The tampon gets pushed deeper into the vaginal canal during penetration, sometimes pressing firmly against the cervix. Here’s what actually happens and what to do about it.
How the Tampon Gets Displaced
During penetrative sex, a penis or sex toy pushes the tampon higher into the vaginal canal, compressing it against the cervix. The cervix sits at the back of the vaginal canal and acts as a barrier between the vagina and the uterus. Its opening is far too small for a tampon to pass through, so the tampon cannot travel into the uterus or get “lost” inside your body. That’s a common fear, but it’s anatomically impossible.
What does happen is that the tampon gets wedged deep enough that you can no longer feel the string. The string may curl up around the tampon or tuck behind it. This doesn’t mean the tampon is gone. It just means you’ll need to work a bit harder to get it out.
Pain, Bruising, and Tissue Damage
The most immediate issue is discomfort. When the tampon is pressed against the cervix during thrusting, it can feel like a sharp pressure or dull ache deep inside. A dry or recently inserted tampon is firmer and more likely to cause problems than one that’s already absorbed fluid, since a soaked tampon is softer and more flexible.
Firm tampons pushed repeatedly against the cervix can cause small bruises or lacerations on the sensitive cervical and vaginal tissue. These are typically minor, but they can lead to light spotting afterward that’s separate from menstrual bleeding. Both partners may also feel friction or discomfort during the act itself, since the tampon takes up space and changes the way things feel internally.
The Bigger Risk: Forgetting It’s There
The most common problem isn’t the sex itself. It’s what happens afterward. If the tampon gets pushed high enough that you can’t feel it, you might forget about it entirely, especially if you insert a new tampon later without realizing the first one is still inside. A retained tampon that stays in the vagina for days can cause a noticeable infection.
Signs that a tampon has been left inside too long include:
- Vaginal discharge that’s yellow, green, grey, or brown
- A strong, foul smell from the vaginal area
- Fever or elevated temperature
- Vaginal itching, swelling, or redness
- Pain or discomfort when urinating
- Pelvic or lower abdominal pain
These symptoms typically develop within a few days. If you notice any of them and suspect a retained tampon, it needs to come out as soon as possible.
Toxic Shock Syndrome
Toxic shock syndrome (TSS) is the risk people worry about most, and while it’s real, it’s also rare. TSS is a life-threatening condition caused by bacterial toxins that can develop when a tampon stays in too long. The NHS lists tampon use as a known risk factor for TSS. Symptoms escalate quickly and include a sudden high fever, vomiting, diarrhea, a sunburn-like rash, dizziness, and confusion.
A tampon forgotten after sex doesn’t automatically cause TSS, but the longer any tampon remains in the vagina, the higher the risk. The standard recommendation is to never leave a tampon in for more than eight hours. If sex pushes a tampon out of reach and you lose track of it for a day or more, you’re extending that window significantly.
How to Retrieve a Pushed-Up Tampon
If you realize the tampon is still inside after sex, the first step is to relax. Tensing your pelvic muscles makes the vaginal canal narrower and retrieval harder. Wash your hands, then squat or put one foot up on the toilet seat. Bear down gently with your abdominal muscles, the same way you would during a bowel movement. This pushes the contents of the vaginal canal downward. Reach in with clean fingers and sweep along the walls of the vagina, feeling for the tampon or its string.
Most people can retrieve it themselves with a little patience. The vaginal canal is only about 3 to 4 inches deep on average, though it stretches during arousal, so waiting until you’re no longer aroused can make the tampon easier to reach. If you’ve tried and can’t get it, or if you’re experiencing any symptoms of infection, a healthcare provider can remove it quickly using a speculum. It’s one of the most routine things they handle, and there’s no reason to feel embarrassed about it.
A Simpler Approach
The easiest way to avoid all of this is to remove the tampon before sex. If you’re concerned about mess from your period, a towel underneath works well, or you can try a menstrual disc, which sits higher in the vaginal canal near the cervix and is specifically designed to be worn during intercourse. Unlike a tampon, a disc doesn’t occupy the main vaginal canal, so it doesn’t interfere with penetration or create the same displacement risks.
