advice PLEASE

I'm 14 and im dating a boy and its almost been 1 year. and i know that im quite young but he is the sweetest kindest boy ive ever met and he makes me feel so loved and i feel safe and happy when im with him. Hes also always there for me whenever I feel sad or upset he always says the right things to make me happy. So this is why i truly love him and he makes sure I know that he loves me too. The only problem with this is that neither of my parents dont know and i know i need to tell them sooner or later but i dont know how to :( please help me
