Hi Jennaflower - do you know who Dr. Drew is? I remember him commenting on this very type of question .... he said you can de-sensitize areas by using toys.....however they can be re-sensitized too ..... his suggestion was that if you are used to using only a toy for a long period of time .... and you know you are about to change to being with a partner (as well) - then to resensitize, that you steer clear of using the toy for at least several days before .... allowing a break from that type of stimulation and if possible from all stimulation for that time. Don't know if it's true, but Dr. Drew seemed pretty knowlegable on all such matters ..... good luck!!!!
