Does anxiety cause early ejaculation?

Blood in semen is called haematospermia. It is alarming to see, and in most men — particularly under 40 with a single episode and no other symptoms — it turns out to be benign and self-limiting, often following inflammation or a minor procedure. Common causes include prostatitis, urethritis, minor trauma, recent prostate biopsy or catheterisation, and sexually transmitted infection. It warrants proper assessment rather than watchful waiting if you are over 40, if it recurs or persists beyond a few weeks, or if it comes with pain, fever, difficulty passing urine, or blood in the urine. In older men it occasionally indicates prostate pathology, which is the reason for the lower threshold to investigate with age. Assessment typically includes examination, urine testing, STI screening, blood pressure, and in older men a PSA test and sometimes imaging. It does not usually affect fertility, and it is not a sign of cancer in most cases. Please see a urologist, and do so promptly if you are over 40 or have any of the additional symptoms above.
