When I masterbate, it’s painful for a minute or two and really stings inside, recently it’s been watery, only a tiny bit comes out. I know this is graphic but am worried, I’m only 14 and will be 15 soon, And, I’ve always had a bit of pain when peeing, I used to pee blood when I was 5 but didn’t say anything and it often hurts when I pee now. My brother has had many kidney problems so good be genetically. I don’t know. I am circumcised also, I don’t know if that helps. Thanks.
