Itch Happens: Why You Itch Down There After Sex
Is your genitalia this week’s guest star on The Itchy and Scratchy Show? You’re not alone. Lots of folks experience itchy vaginas and penises post-sex. Here’s the deal.
Itchy vagina after sex
Friction from sex can cause vaginal itching and discomfort. It’s usually nothing to worry about. But you might have an underlying issue if:
- you have other symptoms
- your vag itches on the reg
- symptoms last more than a few days
Are sperm to blame?
You might be allergic to sperm. Really tho. Seminal plasma hypersensitivity is rare but possible. It happens when you have a bad reaction to proteins in semen.
A semen allergy can affect any part of your body, not just your vag. Reactions can be hard to predict. They can pop up randomly — even if you’re doing the deed with a partner(s).
Symptoms usually kick-off 10 to 30 minutes after contact with semen. You might experience:
- pain
- itching
- burning
- swelling
- redness or discoloration
The latex lining: Condoms can protect you from a sperm allergy flare up.
Latex allergy
A lot of condoms are made from latex. That’s a bummer for folks with a latex allergy. Symptoms can range from mild to severe, depending on your level of sensitivity and how much contact you’ve had.
Mild symptoms include:
- rash
- hives
- itching
- redness or discoloration
Moderate symptoms include:
- coughing
- sneezing
- wheezing
- watery eyes
Anaphylaxis — a potentially life-threatening allergic reaction — can happen in severe cases. Get medical care ASAP if you experience:
- hives
- nausea
- vomiting
- swelling
- dizziness
- confusion
- trouble breathing
Dryness
Some peeps are prone to vaginal dryness. It’s pretty common when your hormones are in flux — like during pregnancy or menopause.
Other vaginal dryness triggers include:
- not being aroused during sexy time
- surgical ovary removal (aka oophorectomy)
- certain meds (e.g., antidepressants and hormonal birth control)
- health conditions like Sjögren’s syndrome (an autoimmune disorder) and diabetes
Here are some symptoms to look out for:
- painful intercourse
- a frequent need to pee
- vaginal pain after penetration
- chronic urinary tract infections (UTIs)
Infection
Vaginal infections — like bacterial vaginosis (BV) and yeast infections — can lead to lots of issues. In addition to itching, symptoms can include:
- fever
- painful sex
- painful peeing
- discolored discharge
- spotting between periods
pH imbalance
Vaginas are slightly acidic. A healthy pH level should range from 3.8 to 4.5. This helps keep bad bacteria at bay.
If your pH level is off, you’ll have a higher chance of getting an infection. Some warning signs include:
- a fishy or foul odor
- burning when peeing
- a thick or unusual discharge
Here’s what might be behind your pH imbalance:
- antibiotics
- semen since it’s alkaline
- douching, which increases vaginal pH
- periods
STIs
Several sexually transmitted infections (STIs) can cause vagina itching. Here’s the lowdown.
Trichomaniasis
This STI comes from the parasite Trichomonas vaginalis. Symptoms tend to show up 5 to 28 days after exposure.
Common signs of trich include foul-smelling discharge and burning during urination. It can also lead to painful sex.
Gonorrhea
The clap is usually asymptomatic in folks with vaginas. But symptoms can include:
- painful peeing
- vaginal bleeding
- abnormal discharge
Chlamydia
Chlamydia is usually easy to cure. That’s good news since this STI can cause permanent damage to the reproductive system if left untreated.
A lot of people don’t show symptoms. If you do, you might feel the burn when you pee.
Genital warts
Genital warts come from human papillomavirus (HPV). Warts range in size and texture. Even if you don’t have warts you can still experience:
- itching
- bleeding
- burning
Genital herpes
There are two types of genital herpes:
- herpes simplex type 1 (HSV-1)
- herpes simplex virus type 2 (HSV-2)
You can get HSV-1 from nonsexual contact. HSV-2 is usually transmitted through sexual contact by a partner(s) who’s contracted the infection.
Both viruses can cause blisters on or near your vag. These little suckers can be itchy and painful AF. You can also have both types of herpes at the same time.
In more severe cases, genital herpes can cause:
- fever
- body aches
- swollen lymph nodes
Itchy penis after intercourse
Rough sex. Dry skin. No lube. All of these factors can take your d*ck to itch town. Here’s what might be going on down there.
Latex allergy
According to the Asthma and Allergy Foundation of America, less than 1 percent of Americans have a latex allergy. Even though this allergy is rare, it can really cramp your condom style.
