Hi lolli.....
The first places I would have her go at Susans are 1.) Introductions, 2.)
wiki, 3.) Sexuality Forum, 4.) Significant Others Forum
This should be a good start. Let her look around, and get involved in areas that interest her. Have her check the Web Directories, on the main page. If you plan on grs, I would at some time have her investigate this, and learn what it is you might be going through.
In short, be open, and honest. Of course, there is always a risk in being very open in relatively new relationships. Use your judgement.
Wishing all the best for you both,
Bev
