Any ideas on why fine long hairs are propping up on my arms, stomach, chest, butt, etc. It's kinda like transparent fur and i really don't like it but idk why i'm getting it?

Puberty

Fur ? Might be becoming a werewolf-stay out of the full moon.

Talk to a doc.

Possibly maybe could be getting your skin ready for a very cold winter???

You should see your doctor.  Could be a hormonal imbalance.
