so yeah the tip of my penis is really wet and is a little red and it burns sometimes after i urinate is it dangerous is it a normal thing im 12 by the way
No, I don't think it's dangerous.
Likely it's just irritated. I'm guessing you're not circumcised? As you approach puberty you'll start having erections more frequently and these can cause little tears in the skin, which can become inflamed.
If so, clean the area, gently, with a mild soap and water. Be sure to "shake it dry" after you finish urinating.
