I like your idea...but make sure you aren't doing it so often that it could be construed as "pressure" by her...especially if she is legitimately trying to figure out her sexuality. By that I mean...don't be doing this every day LOL.
I do believe you two need to have another talk though, now that you've broken the ice. Ask her what she's trying to sort through exactly...be understanding, be supportive, be loving...but ask the questions you need answers to.
BTW, good news about your brace...I'm sure you'll be glad to be rid of it!
