IS "YOU'RE MAKING ME BLUSH" CONSIDERED DIRTY?

I want to write it as a response to a cute compliment to a guy I like who likes me back. It's just that the compliment kinda made my cheeks blush, I don't know why some people say it's dirty..
Would he be weirded out or think I'm being dirty (even though that's not how I meant it)? And is it even a cute thing to say or would you suggest something better to text (if so please say what)?
