I have just turned 18. I suffer from anxiety and im on nebivolol 2.5 mg. I noticed that my semen has turned very watery and kind of transparent since like 2 months, before that it used to be thick. I do not really have other symptoms but im scared of having testicular or prostate cancer. I read that someone with prostate cancer had the same issue. Since then I fear having prostate cancer and im looking for symptoms all the time. I also feel lightheaded but that is since I was diagnosed of anxiety and after taking medicine. My vision is dim at night.
