My girlfriend and I are planning to have a baby, we've been having sex for 3 months, we've been trying alot! My sperm has been looking watery too and I wonder if theres anything wrong with me having kids. I'm a 31 year old man, girlfriend is 21, young and has 2 children of her own, I dont have any of mine. There is nothing wrong with her, we use to go like 2-3 times daily, lately the past month we've gone once a day and now, today I can't ejaculate anymore :$
I think you should talk to your doctor, the problem may be in your testicle and prostate gland, it can be a little inflammation there. You should pass some analysis to determined sperm cell counts in your sperm
