Hello, I'd like to apologize for the ambiguity of my title but I have no idea what my problem is, and thank you in advance for any advice you can give.
For the past month I have been having problems urinating. It is not that I have frequent urges, or that I have trouble going, but that at the end of my urination recently i experience very sharp burning sensations. More specifically it feels as if towards the end of my urination the urine becomes thick, the fluidity ceases and becomes hard to control sprinkles, and leaves a resonating pain for 15-20 minutes.
I have "pushed through the pain" so to speak, as this had happened to me once before and subsided, but now it is beginning to worry me. I am 16 and I am a virgin so it is not and STD and should not be any aging issue. My sex drive is low (not that I'm wanting to have sex but that the actual 'urges' i should be having have dipped considerably probably as a result of the pains; and i have begun fearing to use the bathroom.
More importantly however i think i have found the source of the issue. I have noticed inside my penis (in the urethra) white solid particles. In an experimental masturbation session, (an unfufilling one that ejaculated oddly and with thin semen) a whole array of these white particles came out along with the semen, flaky and comparable to dandruff. They seem to form within my urethra, and may be a source of blockage.
The only thing I have ever heard of that is white and solid/flaky having to do with a penis is smegma, which i doubt is the issue as I am circumcised and shower daily. I have started drinking canberry juice as i've heard it's a magical remedy for these types of things but otherwise I have no clue what to do.
I'm very sorry for the length of my post, and thank you again very much for any help and advice you can give.
