Hi and welcome to HCM.
It sounds serious and you should go to urologist
definitely. It is absolutely abnormal and just need to find is it caused by infection or there can be some recourethral fistula.Or this is just semen going out. YOu dont have to be afraid if doctors. I really suggest to go there. First you should do urethral swab test and then some other tests should be done. WIsh you good health.
