You can always ask about things, or make requests, and your wife can share as much as she is comfortable with sharing. Some people like to share a good deal. Personally, my partner and I share some stuff. We draw a discreet curtain over what we did sexually, usually. As long as we have both discussed our safer sex boundaries, I like to give my other partner(s) their own space. Of course, I can and do ask my partners if they mind if I share some sexual details with another partner, and often the men are absolutely fine with me sharing. Women may want more privacy, while men don't mind their sexual prowess being discussed between me and my female partner lol. Oh, the patriarchy...
But your wife may not want to share much, at all. Personally, as a safety thing, I like knowing when my partner goes to a new person's house for the first time, and knowing what their address and phone number is. And if my partner goes to a fun restaurant, or shopping, or some kind of show, etc., I'd be curious how it was, just like I'd be with any close friend or family member.
But as far as asking for great detail about her emotional involvement right off the bat, I probably wouldn't pry, and wait for her to share, knowing I wouldn't judge her or feel threatened, etc. However, as a newbie, you might be feeling jealous, fearful, threatened, etc. These are things to be discussed. It's OK to ask for reassurance and tell her what you need-- a hug, a cuddle, a quality date, sex (when she's ready), etc.
