Is it normal my pp is hard

no. you are going to explode unless you yell very loudly until it softens

Assuming this is a genuine question, ignore the trolls. You're going to be ok, your body is just going through changes. I would recommend asking your parents for guidance about this.

Just gotta yeet that meat

I'm going to assume this is a real question. You are absolutely going to be okay, what's happening is normal and just something your body does sometimes! Ask your parents or doctor about it if you get really worried, but you're fine!
