How do you... learn foreplay?

This is context is going to make my question sound really dumb, but I've been married for over 5 years. However, I've never felt fully confident in my performance during foreplay, or even really my understanding of such activities. I've never engaged in consuming pornography. Whenever I've seen foreplay discussed online in forums like this, I feel a lack of personal confidence.

Obviously, it doesn't look the same for everybody, and it's personal and really just for what works for my wife and me. But... how do you learn foreplay?

I don't mean to be asking too many questions in this sub.
