Why did it burn?

what does it mean when you are getting fingered and it started to burn

it could mean there was'nt enough lubrication... this can depend on how long you were being fingered. :l

^^what he said. It shudnt hurt.. Shud feel nice :]

You're 14! No one should be getting fingered!! Well, if you're fooling around at least use protection!!!
That being said, maybe he had something on his hands before hand? Hand sanitizer?
Where you properly lubricated during aforementioned fingering? Maybe he was being a little too rough. Somethings to think about...
