Despite pleasure ranking high on the list of reasons why people have sex in the first place, pain often rears its ugly head in sexual scenarios—particularly for folks with vulvas having penetrative p-in-v sex. While any kind of sex act can trigger different types of vulvar, vaginal, or pelvic pain in the heat of the moment, pain after sex can be just as troublesome, both physically and emotionally.

Generally speaking, post-sex pain can come in many forms, from period-like cramps to vaginal swelling, itching, or a burning sensation when you pee, says gynecologist Sherry A. Ross, MD, sexual-health expert and author of She-ology: The Definitive Guide to Women's Intimate Health. Period. And in some cases, a trigger for pain during sex or during menstruation (such as uterine fibroids or endometriosis) can lead to lingering pain after sex, too.

Like with any kind of pain, the first step toward resolving it is identifying what’s causing it. But in the case of postcoital pain, this isn't typically something you should do on your own. As a general rule: If the pain is severe or consistent, your first move should be a visit to your gynecologist or, even better, a gynecologist that specializes in sexual medicine. "In the pelvic region, the nerves get all jumbled, and the pain signals mix and match throughout the process," says gynecologist and sexual-health specialist Angela Stoehr, MD. "Once these signals reach the brain, it literally has to guess where the pain is coming from. So, unless you're examined by a medical professional, it's difficult to really know what's causing it."

That said, there are several common causes of pain after sex that are helpful to note before heading into a conversation with a healthcare professional. And luckily, all of them are treatable in one way or another—which, it's worth emphasizing, is important to prioritize; healthy sex, after all, is pain-free sex from start to finish and beyond.

Below, sexual-health experts break down the most common causes of pain after sex, as well as the solutions that'll allow you to fully enjoy the afterglow of getting busy.

Here are 10 common culprits of pain after sex and how to resolve each one

1. Vaginal dryness

A vagina that's, well, less than moist can create friction during sex that triggers pain afterward, too. And the overall hydration level of your vagina can vary based on everything from the stage of your menstrual cycle or menopause (more on that below) to what you’re eating and drinking, and the quality of your sleep. In terms of penetrative sex, rushing into things is also likely to result in a desert-like situation down under, according to Dr. Ross.

Treatment: Arousing outerplay and lubricant are your BFFs here. When it comes to choosing a lube, Dr. Stoehr recommends a silicone-based one: "It's the slickest variety and the least likely to cause reactions because it can't absorb into the vagina." And as for amplifying arousal, don’t be afraid to take things into your own hands (literally), and show your partner how to turn you on.

2. Pelvic-floor muscle dysfunction

The pelvic floor, or that sling of muscles running from your pubic bone to your tailbone, plays a big role in penetrative sex, as it needs to lengthen or relax to allow for penetration into the vaginal canal, says pelvic-floor physical therapist Marcy Crouch, DPT. "If the muscles in the pelvic floor are too tight, or they are in spasm or contracted, penetration will be difficult or painful. And depending on the dysfunction of those muscles, the pain can linger for hours or even days," she says.

Treatment: Releasing those pelvic-floor muscles is the goal, which Dr. Crouch says you may be able to achieve with diaphragmatic breathing, deep squatting, or even the "happy baby" yoga pose. But, generally, seeing a pelvic-floor specialist to develop a treatment plan is your best mode of action. They can advise you on the kinds of pelvic-floor stretches and exercises that would make the most sense for your situation after assessing your pelvic floor with a biofeedback device.

3. An acute infection

Whether it's caused by yeast or bacteria (think: sexually transmitted infections like chlamydia and gonorrhea, bacterial vaginosis, or a urinary tract infection), any kind of infection in your nether regions could lead to pain after sex. "If the pain came on suddenly, is quickly worsening, or you notice other symptoms like body aches or fever, an infection is likely to blame," says Dr. Crouch. And it's important to act fast, in that case: If left untreated, certain STIs can progress into pelvic inflammatory disease (PID), which is an infection of the uterus, fallopian tubes, or ovaries that comes with symptoms like bleeding, heavy discharge, and fever.

Treatment: If the symptoms are new to you, in particular, seeing a physician is critical to properly diagnose the source of the infection, says internal-medicine physician Monique White-Dominguez, DO, who heads up the sexual-health program at Sameday Health. Treatment usually includes an anti-fungal or antibiotic, depending on the nature of the infection. As a precaution, Dr. Ross also recommends getting STI check-ups in between sex with different sexual partners.

4. Menopause

This stage of life comes along with a natural dip in estrogen production, which can lead to vaginal dryness or vulvo-vaginal atrophy, or the thinning and inflammation of the vaginal walls, says Dr. White-Dominguez. And either scenario can trigger soreness with sexual penetration that sticks around long after the sexual act is done.

Treatment: Talk to your doctor about topical estrogen products or suppositories containing Dehydroepiandrosterone (DHEA), a hormone that can boost your production of estrogen and testosterone. And if you want to go the drug-free route, Dr. Ross suggests the MonaLisa Touch, which is a 5-minute treatment that uses laser energy to stimulate the vaginal wall.

5. Penis size

So, yes, apparently there is a such thing as overly big dick energy, which can explain soreness after sex. “‘Bigger is better’ is simply not the case for a vagina that can’t tolerate a long or thick penis,” Dr. Ross says.

Treatment: This scenario isn't necessarily a lost cause—you'll just need to ease into things with your well-endowed partner. “The vagina does stretch depending on the size of the penis,” Dr. Ross explains. “But, it may take time, patience, lubricant, and lots of open communication.” Another option for situations where length, rather than girth, is the issue? Penis bumper toys, which slide down the shaft of the penis and decrease the available real estate for penetration.

6. Latex allergy

If you’re allergic to this material, any sex with a latex-containing condom (which is a lot of them) can cause vaginal swelling, itching, and pain during and up to 36 hours afterward, says Dr. Ross. And it's worth noting that this allergy can develop slowly. So, even if you’ve been using latex condoms for years, you may find that you've become allergic to them over time.

Treatment: You may need an over-the-counter antihistamine or hydrocortisone cream to treat an active reaction. To prevent one from occurring in the future, Dr. Ross recommends switching to polyurethane condoms, which are made of plastic. But, be warned: Because they don’t have the same stretch as latex, they may be more likely to slip off or break during sex.

7. Ruptured ovarian cyst

“If you are ovulating, chances are there is a large ovarian cyst waiting to burst and release the egg,” Dr. Ross says. “Aggressive sex, exercise, or a spontaneous rupture can cause this cyst to release its fluid contents along with the egg, causing noticeable pain.”

Treatment: Even though it sounds scary, this is actually a normal physiological phenomenon known as mittelschmerz, Dr. Ross explains. It’s best to consult your doctor and have a pelvic ultrasound to help make this diagnosis. (If the pain becomes severe, however, head to the ER, as that could signal excessive bleeding from the rupture, which may need to be controlled medically.)

8. Certain sex positions

According to Dr. Ross, it’s totally normal to experience some discomfort after doing it in certain positions. Doggie style, for example, is a bit rougher on your uterus and ovaries than missionary, since it allows for deeper penetration. (Not to mention, some of the more physiologically advanced sex positions—like reverse cow-rider or a sitting 69—could leave you sore in various, er, non-genital parts of your body like your glutes or inner thighs.)

Treatment: Pain that comes from a certain sex position will usually dissipate on its own. To keep it from happening again, take the time to get to know your body and discover which positions are most comfortable to sustain—and steer clear of the ones that hurt, even in the slightest bit.

9. Breastfeeding

For new mothers, breastfeeding may very well be the culprit. As with menopause, when you’re breastfeeding, your estrogen levels dip—in this case, to promote milk production. And a drop in estrogen can lower your libido, self-lubrication, and blood flow to your nether regions, creating a perfect storm for pain both during and after sex.

Treatment: The physical (and emotional) challenges that come along with breastfeeding will improve with time. For now, a little extra lubricant should do the trick, Dr. Ross says.

10. Emotional trauma

If you've experienced any kind of pain with sex in the past, you're more prone to continue experiencing this (very real and physical) pain, even absent a current medical trigger. "In the instance of persistent pain, the brain begins to associate that area of the body with 'danger' and 'injury' when there may not be an acute injury process happening," says Dr. Crouch. "Fear, anxiety, and anticipation of pain can actually increase and up-regulate the pain and tension."

A similar response can occur if your initial intro to sex was through a religious or cultural perspective that disregarded pleasure for vulva-havers. "People who were taught that their vulvas were a 'no-fly zone'—'don't touch, don't look, don't play'—can have a hard time flipping off that switch and allowing access to that area for intimacy," says Dr. Stoehr. The resulting hesitation or fear related to sexual intimacy can actually cause or worsen pain surrounding sex.

And the same thing goes if you've experienced any kind of psychological or emotional trauma related to sex. "This can trigger vaginismus, or a subconscious contraction of the pelvic floor with attempted penetration, which may be very painful," says Dr. Stoehr.

Treatment: Given that the fear loop relating to sexual pain can lead to sexual aversion over time, Dr. Stoehr suggests seeing a sex therapist. Being able to communicate what you're feeling and learn techniques to reframe unsupportive thoughts can help you harness your full sexual potential—that is, to enjoy sex as pleasure without any of the (unwanted) pain.
