Thank you for asking. I can understand the distress you are through. I appears to be a problem of premature ejaculation. Spontaneous discharge in night, semen in urine, etc are common presentation. Multiple factors such as stress anxiety, masturbation habit, pornography use, lifestyle associated risk factors, etc needs to be explored in details. These have an important implications on one's sex life. A detailed information regarding these is needed. If needed suitable medication and instructions can help you overcome this problem. Don't worry, it does not cause weakness. That is total myth.
