True, I guess it may appear to your spouse as unusual, but perfectly harmless IMO.
I didn’t make her aware as personally I wasn’t aware of it, my sisters have them too. Its important to accept your spouse for who they are(within reason), my ex never mentioned that she suffered from HPD and was obsessed with flirting with strange blokes to the point of destroying her marriage, lying about everything she thinks she can get away with and thinking she’s above Allah himself, accepting your husband has a collection of soft toys? Not the end of the world.
