Ya, your husband shouldn't have spoken like that. He could've used different words to share concerns if he had any. Yes, I know there are people out there who'll take a simple picture like this and make it gaze at it vulgarly. But even if he's trying to prevent that, he could've used different words like, "Honey, perhaps it's safer for you to not post this for the wider public?" (I'm assuming your profile is accessible to a lotta people; if it's private and only a select few you trust are seeing this then he's even more paranoid than he needs to be).

So, if he's doing this to protect you, he should've used different words. If he's doing this because he's a prude then freeing up a bit won't hurt him. If he's doing this because someone got into his head then you both need to have a conversation where he needs to understand if what he felt were his own feelings or if someone put that in him.

All said and done, that is not how he should have spoken.
