what happens to your body after sex

We'd like to say everything about sex is always wonderful and perfect, but sometimes weird stuff does happen. You may feel a bit strange after or see strange physical reactions. You may even feel some burning or pain.

According to the American College of Gynecologists and Obstetricians, as many as 75 percent of women will experience painful sex at some point in their lives. We like to joke about having had sex so good we can't walk the next day, but what about if things are severely painful or inflamed? Or if there's burning? Or bleeding? When do we start to worry?



We asked the experts about what happens to your body after sex, and how to determine if you need to see a doctor or if it's a natural response from your body.

1. You sweat profusely.

You may find yourself sweating heavily for a long period after a vigorous session.

"As with all forms of exercise, sexual activity causes your body temperature to rise. Your heart will slow down after sex and deliver less blood to the skin. As the heat accumulates in your muscles, it causes your blood temperature to rise, which is why you may sweat much more after sex than during," says cardiovascular surgeon David Greuner of NYC Surgical Associates.

2. Your heart rate increases.

Anything that raises your heart rate counts as cardio, and sex is a great workout with each orgasm equivalent to approximately one mile of cardio.

"The more energetic you are during your session the more cardio benefits you receive and will keep your heart pumping harder, longer. Another common reason for an elevated heart rate is dehydration, so increasing water intake after a robust round of sex will help get you cooled down and back on track," advises Greuner.

3. You experience lingering pelvic pain.

Feelings of pelvic pain and pressure can linger way after intercourse, with some causes being less serious than others.

"Particularly in women who have had children, a condition called 'pelvic congestion syndrome' can cause severe pain, particularly on the left side, and most commonly with deeper vaginal penetration. A situation analogous to varicose veins can occur in the pelvis, and due to the hormonal surges occurring during intercourse, veins can become engorged, leading to increased sensitivity and pain. While not a dangerous condition, you may want to have it checked out if the pain inhibits your pleasure," Greuner warns.

4. You bleed.

Sometimes you think your period ended and those contractions bring a few last drops out. But it's nothing to worry about. If it happens often though, see your doctor; it could be a variety of pelvic conditions. 

"It can be totally annoying when your period doesn't do what it's supposed to do, especially if ends up with a few extra days of flow pushed out by cramps that keep you free from wearing your pads and tampons and maybe even sex. It can be totally normal, though, because it is pretty amazing that it knows what to do every month. But if it persists, it's a good idea to talk to a doctor to make sure there isn't another pelvic condition causing it," says OB/GYN Dr. Lisa Masterson.  

5. You feel burning.

It's not super common, but it doesn't mean anything terrible if it happens. It could just mean your vagina is inflamed. But if you are worried about it being an STI or if symptoms continue, see your doctor.

"Nothing should be burning in that area. So if it is burning and painful, contact your doctor," warns Masterson.

6. Your vaginal secretions increase.

After having sex, excessive vaginal secretion is normal.

"It means that you might have experienced orgasm. Your body has just secreted a lot of happy juice,'" says Dr. Renjie Chang. For older women after menopause, due to estrogen reduction in the body, her vaginal secretion becomes less, causing dryness and vaginal atrophy (shrinkage).

7. You get cramps.

Painful sex doesn't happen often, but sometimes it does. This is sometimes just cramping from uterine contractions related to your orgasm and is nothing to worry about. However, if it happens all the time, talk to your doctor. You could have fibroids or other more serious issues, such as uterine cancer.
