Howd you tell your parents about your first bf/gf?

me and this boy have been talking...a LOT. and he kissed me too last night. he pretty much told me hes going to ask me out once we go out together a little more. im ecstatic, but how do i tell my parents? they have said nothinggg about boys, we never talk about anything like that. never had a bf. im 15. i know my parents will be all over him once they know he exists, do i even tell them? thanks
