Not diagnosed yet but suspect symptoms

Hi,

I am just new to the community and I am under stress on noticing few symptoms related to bladder. I am a male in early 30's unmarried and I have recently experienced certain symptoms which holds potential to make me extremely worried. Since last two weeks my urine flow has become little weak and I can feel it. I have noticed less urine output and frequent urge to urinate after few intervals in day. After urine there is little dribling and at close inspection in the urine, I can see white tiny particles floating in with few minute bubbles. My urine color is mostly transparent to pale yellowish. As I recently migrated to cold region, I drink less water. I do not feel any pain or uncomfortability while urinating but what makes me worry is Erectile dysfunction which I have recently experienced and on top of that I do have metallic sort of taste in my mouth. I have been healthy sexually and have never experienced ED in my life before. I do have bleeding haemorroids and chronic constipation in my bowel. Besides I am not a smoker and do not consume alcohol. I am really worried and I suspect is it a kidney disease or infectious bladder. Have any one faced such condition. Are these all early symptoms related to kidney disease?
