Good day. I haven't had sex in a while. Decide to do it last night. But there was blood in my ejaculation and actually urine blood after having sex?

Hematospermia. Hematospermia (blood in th semen) is almost always from a benign cause such as inflammation or infection in the prostate or seminal vesicles. If symptoms persist, you may need to see a physician for antibiotics. If urine is bloody, see a urologist.
