What is the hidden psychology behind guys sending photos of their outfits and asking to send them to each other?

I was recently chatting with a guy who often offers to send me pictures of his outfit of the day, all of them are the kind of pictures that are taken from top to bottom and show only the outfit without showing his face. And, he always expects me to share my outfit photos with him every day as well. What the hell does that mean? I find it very strange! What's his motive behind asking me "what are you wearing today" and asking me to take pictures of it?

Maybe he's trying to get a sense of what you're wearing but is too embarrassed to ask for a photo directly, so he sends his own over first, implying that you should send one back as well. Do you think that's the case?
