For me I don't think it's disrespectful to post, especially since she has show on a public beach everything I have posted here. But rather I am proud to show my hot wife who I am lily to have, who works very hard to maintain herself.
Certainly wives always worry and are self conscious of their looks, but taking pictures that flatter and highlight how sexy they are definitely enhance their self imagine. I can take pictures that would make any woman look sexy or use angles backgrounds that make any woman look unflattering. Preparation lighting, angles, backgrounds, poses and highlight your ladies best attributes
Take many and delete all but the very best, the resulting pictures will surprise your wife and she will not mind the odd anonymous post of a boob or ass
