Sexually transmitted infections (STIs) can often be silent, meaning there may be no symptoms at all. However, when symptoms do appear, they can vary between men and women. Common symptoms in men may include unusual discharge from the penis, sores or warts on the genital area, burning sensation during urination, and itching or irritation inside the penis. Women may experience unusual vaginal discharge, sores or warts on the genital area, burning sensation during urination, itching or irritation inside the vagina, and pain during intercourse. It's important to see a doctor if you notice any of these symptoms. Avoid having any kind of sex until you have been checked by a healthcare provider. STIs are highly contagious and can lead to serious health complications if left untreated. If a current or former sexual partner informs you that they have an STI, it's crucial to get tested even if you don't have symptoms.
