Hello,
Yes, some of the causes to your problem may be age, frequent ejaculation,
low sperm count,
retrograde ejaculation (semen does not comes outside rather goes back, maybe in bladder), nutrient deficiency, Sexually Transmitted Diseases like
Gonorrhea and many more.
Now, in a person having watery semen, any one of the causes can be the culprit. It is important to know the cause specific to you.
Considering other symptoms present in you like "hurt to urinate" and history like "unprotected sex with several women", I would like to advise you to do these tests:
1. Semen Analysis
2. Complete Blood Tests
I also strongly advise you to do the followings:
1. Lifestyle changes
Quit smoking cigarettes.
Lose weight if you’re
overweight.
Reduce your alcohol consumption.
Exercise regularly.
2. Reduce stress
3. Get sufficient rest and sleep
4. Do not
masturbation.
5. Dietary changes
Consuming foods rich in zinc, selenium, vitamin C,
vitamin E, and
vitamin B12 can help improve sperm quality.
Post another question with results. Any doctor can follow you up.
Do not worry. Follow the above guidelines. Its too important and may improve your semen quality.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Dipan Samanta, General & Family Physician
