Karen, yes, I went thru this very same situation when my daughter turned 18 and moved in with me full time.

First, if you're a closet CD like me, tell people only on a "Need to know", basis. I told my daughter while we were out on a walk in a deserted park. So, either of us could do or say whatever we wished with no interruptions in complete privacy. If it doesn't go well, as it didn't with me, we discussed a DADT arrangement so she won't ever have to see me dressed. And, except for one accidental meeting, she hasn't.
