Such symptoms must be examined by a urologist to exclude other potential causes such as infections or skin diseases. 

You are declining from what is known as post-void dribbling. It's a situation when a few drops of urine come out after you go to the bathroom. This can be the case for both males and females. Most of the time it is not dangerous, and it can come from different things like the bladder not emptying fully or the muscles being weak. Drinking plenty of water is sometimes the solution. If you're not having any other symptoms, it's probably nothing to freak out about.

The presence of blood in semen, known as hematospermia, can have various causes. While it's often benign, it's essential to consult with a healthcare professional for a proper evaluation. Potential causes include infections, inflammation, or structural issues in the reproductive system. A medical examination and, if necessary, further tests can help determine the underlying cause and appropriate treatment. Don't delay seeking professional medical advice for this issue.
