The burning sensation when peeing after sex is commonly caused by irritation or inflammation of the urinary tract or genital area. This can be due to several reasons:
- Urinary Tract Infection (UTI): Sexual intercourse can introduce bacteria into the urethra, leading to an infection that causes burning during urination, frequent urges to pee, and sometimes cloudy or strong-smelling urine. UTIs are more common in women due to the shorter urethra.
- Sexually Transmitted Infections (STIs): Some STIs like gonorrhea, chlamydia, or trichomoniasis can cause burning sensations when urinating after sex.
- Lack of lubrication and friction: If there is not enough natural or artificial lubrication during intercourse, friction may irritate the urethra or vaginal tissues, causing a burning feeling after sex.
- Allergic reactions or irritations: Allergies to latex condoms, spermicides, lubricants, lotions, or perfumes can cause burning and irritation in the genital area.
- Yeast infections or bacterial vaginosis: These infections can cause burning pain during or after sex, affecting urination.
- Prostatitis or penile injuries in men: Inflammation or injury to the prostate or penis can lead to burning sensations during or after sex.
Burning after sex can vary based on the underlying cause. Temporary irritation from friction or lack of lubrication is usually harmless and resolves quickly, but persistent or severe burning may indicate an infection needing medical treatment.
