One more pagination trouble

Thanks for helping, i did solve my last pagination problem :-)
I guess you start thinking I have a rather complex book!!
I have another trouble with it!
I want the first page of each chapter to be odd even if i will have to 
insert some blank pages sometimes.
Example :
Chapter 2 ends on page 15 so i insert a blank page 16, so that chapter 3 
starts on page 17

I will appreciate any kind of help on that!
Thanks
