Hi there ~
I understand your concerns. It seems like you have the urge to urinate and the pain in your penis subsisted after urinating as well as the fact that you see pus and blood in your urine. I advise you to consult a urologist
or a local qualified doctor who can examine you, take a good history, do a physical examination, and perform a thorough investigation like laboratory tests as well as probably imaging studies if necessary i.e. CT scans or MRIs. I hope this is nothing serious. I hope the advise helps. I recommend that you continue to drink plenty of fluids. I hope this helps.
Take care and have a lovely day!
