Need help with the X-Mas list PLEASE!!!

So I'm a gent, and my best friend is a lady. Wanting to get her something for Christmas that she would really enjoy and not buy herself, I asked her what she would really really like to have and to name the first thing off. Well that first thing was a sex toy, I have no problem with getting it for her its just that I have no idea on how to pick one for her.

Please help, I know its a VERY odd request but I can't go to anyone else and ask this.
