Another cause of pruritus ani is sexually transmitted infections, particularly herpes, gonorrhea, and chlamydia, according to Ehsan Ali, MD, primary care physician in Beverly Hills, Calif. These STDs are common, especially in people who engage in anal sex without the use of condoms, says Ali. STDs cause inflammation in the rectal area, which can cause itching. Herpes or HPV can cause warts to appear and further prompt itching and burning. STDs can also cause rashes, discharge, or penile and testicular pain. If you suspect STDs are the culprit, see your doctor immediately to determine proper treatment.
Oftentimes the compulsion to scratch down below can be due to eczema, a skin condition that appears to be a red, scaly rash that can cause persistent itching. While the cause of eczema is unknown, it has been linked to an overactive response by the immune system and can be triggered by allergies and asthma, according to Alan Park, MD, dermatologist, and founder of DermWarehouse. This condition can also be aggravated by external factors, such as certain weather conditions or household products like soap and detergent. Park says that the problem is usually treated with topical steroid cream, which can take care of the itching very quickly since it lowers inflammation.Related: Do You Wipe Properly?
3. Fungal Infections
Yes, fungal infections! The one place where you would least like to have fungus is the place where you can get a lot of it. It’s no secret that fungus lives on our skin; however, the place fungus thrives the most in is in warm, moist, airless areas like your underwear. While the body usually does a good job of fighting off the invaders, it can be off its game if you’ve been sick lately, overstressed, or get particularly sweaty down there. For treatment, your doctor will most likely prescribe topical or oral anti-fungal medication. You can also try to swap your current underwear for something more breathable.
2. Laundry Detergent
Laundry detergent can also be the cause of an itchy rash on your behind. The irritating chemicals found in laundry detergent can lead to contact dermatitis, which is a skin condition that causes red rashes and mild to severe itching. The reaction is more likely to occur in spots where your clothing gets damp with sweat, like your groin. Prevent contact dermatitis by switching to fragrance-free and dye-free detergent.

Your diet can also play a huge role in why you find yourself trying to scratch that itch. For instance, coffee is known to loosen your anal muscles, and that can cause stool to leak out, thus triggering the itch. Other causes include tea, cola, energy drinks, beer, chocolate, nuts, citrus fruits, tomatoes, spicy foods, and dairy.
