Hello, I am 16 years old, and a male, Yesterday I had used the bathroom and towards the end of me peeing i felt a weird feeling and tingle towards the end of me penis and it was disrupting the rest of my urination, I noticed my pee woudl get red towards the end of my pee, but not at the beginning, and through out that day the pee got even more red. but today it isn't as red, but this tingle in my penis won't go away and I constantly feel like I need to use the bathroom, I am hoping this isn't a kidney stone, I have no back pains, just a tingly penis.
