I've never actually come out and said it. But I think they all know at this point. I'm 28, and my last relationship was at 18. I've always been very clear about not wanting kids (first time I said it was during the second grade, and I'm pretty sure everyone believes me by now), and in the last years I've been very clear that I like being single and I don't want a relationship. I've just never defined it. My parents pretty much let me be, they don't pry. If I wanted to talk about it I'm sure they'd listen, but I don't feel the need to say anything more. Every time I say I don't want kids or that I don't want a spouse they're like "okay". But they're basically like the most open and accepting people ever, so I'm not worried. I think they are a bit disappointed about not getting grandkids from me, because I'm the eldest and my younger sisters aren't very enthusiastic about it either (my youngest sister doesn't want any, my middle sister doesn't say she doesn't want kids but she's not in any rush to do it before she's 30, so we'll see), but their basic attitude is "it's your life, do what makes you happy".
