Not sure if this was out there under this topic, but I just read a neat book on the subject. It's called "Male Chastity Challange Workbook for Loving Couples " by Darius Knight.
The book has 31 chapters, one fir each day, and each day has a different activity for each partner with the male being locked all month til the end, and the woman receiving as many orgasms as she can handle.
Like I said, I may be late to the party & this was discussed. Book is on Amazon.
