A watery, thin penile discharge often indicates urethritis, which is a common and highly treatable inflammation of the urethra, frequently caused by bacterial infections. The capsules you mentioned are herbal supplements for sexual performance and will not cure an infection. Please do not take them for these symptoms. Instead, you should consult a doctor or urologist for a simple test. If an infection is found, it is easily cleared with prescription antibiotics, such as doxycycline or azithromycin. Please avoid sexual contact until you are evaluated and treated to prevent spreading any potential infection. This is a very common issue, so there is no need to panic.
