JoanWMichelle,
It is wonderful that you are now old enough to be able to give your informed consent to clitoral surgery. Since, even with the latest techniques, there is still a possibility of loss of erotic sensation it is essential that this be your choice.
There is a board that is used primarily by adult women with CAH. http://www.InsideTheWeb.com/messageboard/mbs.cgi Some of the women who post on that board were permitted to make the choice for surgery for themselves and have shared their experiences..
I wish you well.
Joan
