What you are talking about is watery semen
, not watery sperm. Sperm makes up only a small percentage of the semen you shoot, maybe about 5%. Your ejaculation consists of sperm mixed with a few other fluids.
There are various reasons for watery semen.
- It could be your diet. For example, perhaps you are not getting enough protein. Or perhaps you are lacking in carbohydrates and sugars.
- The reason could be frequent ejaculation -- perhaps you are masturbating or having sex a lot.
- Or it could be that you have a low sperm count -- to verify that, you would have to ask your doctor for a test.
My guess is that your watery semen will not last for long: it's a natural occurrence that most guys notice from time to time and it just goes away when you stop worrying.
My best wishes.
