I recommend that you visit a urologist to discuss your premature ejaculation and erectile dysfunction problems. Having the correct diagnosis and a treatment strategy designed for your particular symptoms is a must. Moreover, a urologist can treat your issues with the semen quality and color for you. 

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.

You shouldn't usually see­ blood in your urine after turps. This abnormality can arise if bladde­r or urethra irritation occurs. Infections or kidney stone­s commonly trigger this issue. See­k medical advice promptly if accompanied by pain, fe­ver, or persistent occurre­nce. Increase fluid intake­ and abstain from spicy cuisine for relief. With prope­r care, your body's natural healing mechanisms will like­ly resolve the condition.

In that case you need to consult a sexual health specialist. Convey your concerns to them for proper evaluation and remember that sexual health concerns are common and can often be addressed with the right guidance and support
