Dear user, Thank you for writing to Chat Doctor. I understand your concern about blood in semen after masturbation. This suggests possibility of injury in the way of tube of urine/ semen. I suggest seeing urologist for the same. Avoid masturbation for one to two weeks. Go for safe practices of masturbation to avoid injuries. Regards.
