Do I have an STD or worse?

Patient: I have recently had unprotected sex with a girl that I know and everything was fine but now I’ve noticed blood in my semen after masturbation and also little dripping in my penis after urination, what could this be? Thanks and I’m going somewhere after I get off work I just have to know

Symptoms: Discomfort while urinating and also dripping after urination also blood in semen after masterbation
