ok so last night, my inside lips (my minds gone blank and cant think what theyre called ((inner labia is it??)),) have been itchy and dry, so i have been rubbing them with my nikkers quite roughly, and then when my boy friend touched me there that night it REALLY stung!! like really hurt, what is this?
i know its not an STI or anything as i have been checked..
so i really have no idea what it is, can anyone shed a little lighton the situation?

there is no discharge or blood or anything
