Feeling sick after sex? You're not alone. Sex can leave you feeling many things—relaxed, content, sweaty, or even hungry. But while feeling all of the emotions post-orgasm and working up a sweat or appetite is common, some of the more physical symptoms aren't - and might indicate that it's time for you to book a visit to your GP.
Enter stage right, feeling sick after sex. The symptom is actually a lot more common than you'd think, according to the experts we spoke to for this piece, that said, they emphasise that it's one post-sex symptom that you shouldn't ignore.
Doctor Shirin Lakhani, an intimate health specialist at Elite Aesthetics, says: "Nausea after sex affects both genders. Although it’s impossible to put a figure on exactly how many women are affected, many people across the UK find themselves impacted by this.'"
For her take on why exactly you've been feeling sick after sex, alongside the expert opinions of gynaecologist and Medical Director Lauren Streicher and NHS sexual health nurse and presenter of Channel 4 show The Sex Clinic Sarah Mulindwa, keep scrolling. They've also shared their tips on how to stop the symptom, too.

Am I feeling sick after sex because we've conceived?
Trigger warning: topics of baby loss.
There is a (rather worrying) common misconception that feeling sick after sex is an indication that you've just successfully conceived.
In Lakhani's expert medical opinion, this is not true or physically possible. "Remember, it takes much longer than five minutes for the sperm to fertilise the egg and implant", she says. So if you're feeling nauseous straight after sex, no, our expert does not think it's a sign that you're newly pregnant, and similarly no she does not think it's a sign that you're suffering a miscarriage, either.

Why you're feeling sick after sex
You're not pregnant. So why exactly might you find yourself feeling sick after experiencing sex?
According to Lakhani, there are a whole host of reasons that could be at the root of the problem.
1. Vasovagal syncope
One possibility is vasovagal syncope, which occurs when your partner penetrates you particularly hard and hits your cervix. "The cervix is full of nerve endings. The vasovagal response occurs when the vagus nerve is stimulated, causing a lower heart rate and blood pressure. This, in turn, can bring on nausea," the intimate health specialist explains.
Plus, it's important to note that your cervix changes throughout menstrual cycle phases, dropping lower during your period, which means you may be more susceptible if you get intimate during penetration.

2. Dehydration
Are you one of those individuals who frequently gets home from work only to work out that you haven't drunk a single sip of water all day? Dehydration can cause a whole heap of health problems and interestingly, feeling sick after sex is one of them.
Lakhani says: "Whether it's dehydration, nerves, or actual anxiety, post-sex nausea could be your body’s way of telling you that something isn’t quite right."
If you suspect that it is nerves getting the better of you, do read our guide to stress vs anxiety to work out which it may be, and try to implement stress management techniques such as breathwork training, meditation, and temple massage.
3. Endometriosis
If your nausea after sex is accompanied by pain, it may be a sign of a more serious condition such as endometriosis, pelvic inflammatory disorder or a Urinary Tract Infection (UTI), says Lakhani.
It's not uncommon for women with the above conditions to experience painful intercourse, with other causes including cervical infections and fibroids. Do visit a doctor if you suspect this might be the case.
4. Mental health
Probably not you were expecting to read in this section, but do bear with us.
Lakhani says that if you’ve ruled out all of the potential physical medical triggers that could be causing your nausea, it might be time to look inwards and address the psychological ones. More on exactly how to do that further down this article.
5. Sex going on for too long
Did you know? According to Mulindwa, the most common cause of nausea is sex going on too long.
"Around two-thirds of women struggle to climax through intercourse alone and sex can drag on if you are determined to both end with an orgasm," she details. The best way to avoid this, she shares, is to ramp up the foreplay.
Joint orgasm (and no nausea), here you come.
6. Over vigorous sex
FYI, over-vigorous sex can also cause nausea. "We are not talking about deep penetration here but more head shaking and general movement," shares Mulindwa.
If you are moving too much - back and forth or up and down or side to side without a break - it can cause a feeling like car sickness or seasickness, she warns.
How to stop feeling sick after sex
1. Go gently
First things first—and we're sorry to be the bearers of bad news—but make sure that sexual penetration isn't too hard. This covers fingering, penis-in-vagina sex and any form of vaginal penetration.
Plus, ensure that the position you're trying doesn't feel too forced (this guide to the UK's favourite sex positions might help).
Remember, your body is a temple and all that, and treating your body with love and respect is pretty essential for making sure you don't hurt yourself.
2. Stay hydrated
Simple, but essential: make sure you're drinking enough water throughout the day.
Did you know? Your body is composed of around 60% water, so it's really key to feeling your best.
Try this: Make keeping those hydration levels high simple by keeping a reusable water bottle at work and in your bag, or investing in one of the nifty hydration reminder bottles, which visually prompts you with how much water you should have consumed by what time.
3. Get checked
If you're having gentle sex and keeping hydrated, it might be time you got yourself to a doctor to make sure you haven't got any underlying conditions that have gone undiagnosed, says Lakhani.
This could range from anything like endometriosis to PCOS.
4. Address how you're feeling
Sometimes, you end up feeling a bit icky because of an orgasm causing your uterus to contract in a certain way, in turn creating a visceral response in the form of nausea, adds Streicher.
Let's get real for a second. Ask yourself the following: do you honestly feel comfortable having sex? Deep down or subconsciously, are you hiding feelings of unease or unhappiness? Lakhani suggests that, if the nausea is really persisting and you've addressed all of the above doctors, it might be time to speak to your doctor or specialist.
5. Use some lubrication
The simplest and easiest way to improve sex and limit nausea if you suspect it might be caused by over-vigorous, prolonged, or deeply penetrative sex, according to Mulindwa? Use lots of lubricant (read our guide to the best lube, here).
“Lube makes sex better whatever your age - it's a myth that it's only for people who are struggling to self lubricate naturally. Sex is always better when it is slippery - the wetter, the better - particularly if you both like to go for a long time.
6. Switch things up
“If your problems concern deep penetration, switch positions and try to have intercourse in positions where you can control how deeply you are penetrated and therefore protect your cervix from getting hit. One good way is to have sex on your side and also advise your partner to go easy on the deep thrusts.
“The solution to over-vigorous sex is to slow down and take it easy. Avoid shaking your head too much and enjoy more relaxed lovemaking.
Is it normal to feel sick right after sex?
Short answer: it depends, but the three experts share that it is probably worth checking in with your Doctor about, if the symptom happens more than a few times.
You should definitely book an appointment with your GP if you're drinking loads of water, fully relaxing into sex, and know you don't have any underlying female health conditions like endometriosis or PCOS, as something may be amiss.
What to do if you're continuously feeling sick after sex
If you are experiencing any type of noticeable or recurring pain during sex and feel nauseous after intercourse regularly, do contact your GP or gynaecologist.
