Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. The main symptom of retrograde ejaculation is that there’s very little or no semen when you have an orgasm. That’s because the semen found its way into your bladder instead of your urethra. It may be caused by diabetes,multiple sclerosis, Parkinson’s disease,spinal cord injury or trauma to urethra etc. But in your condition it is due to anxiety mostly. So don t worry some times increased frequency of masturbation in a day probably won t produce any semen. Still have doubts please consult your physician he will examine and treat you accordingly. Hope I have answered your query. Let me know if I can assist you further.
