Okiiiiiii....
Sooooo... you want to train your wife to be lustier/more responsive than she is now...

Sooo... there's an old saying... "Do unto others as you would have them do unto you"
This simply translated to: YOU need to GIVE before you GET!!!
Soooo... if you want you wife to be better in bed... that process starts with YOU...!!!

That's right ... if you are good in bed...and show her all the wondrous things that she can enjoy...
She will benefit from your skills and both of you will be much happier in the long run... E..E..E...!!!
