Welcome to

The conversation you had sounds very, very, very familiar. Not the words exactly, but the tone. It reminds me of the stories we've heard from many couples when one or the other wants to explore sex with others. Nothing too direct, but a mentioning of things that one likes to open the door without risking hurting the other.
It's time to have an open conversation with her about her wants and wishes and then express your own.
Talk! You'll both appreciate it.
