Also done that, we're really on the same page bro
My wife never had any "toy" and would be totally unable to even consider buying one by herself. I didn't ask her opinion and made the surprise to give her one of those high-end classy vibrator. I gave it near the end of one of our scheduled "session", I had just come but her not yet, at a moment she was really "into it". She tried it immediately but it was not 100% successful, I didn't pressure her to use it again but she did and got used to it.
Now she's using it on a regular basis, enjoying it and reaching O very easily.
She told me she was touched by the present, especially the fact that I had made the (not so nice) package myself 😅
