In mid-July, my 3 months will be over, and I will decide what to to do. Here is my current thinking:
1. End the chastity - quite possible.
2. Extend the chastity, for say another 3 months.
3. Permanent chastity - very unlikely!
4. Ruined orgasm, then continue for 3 months. Normally, after a ruined orgasm, I need to do a full orgasm, so this would be intense on the day. Likely.
After a (possible) 3 month addition, I would have a similar review.
6 months sounds a nice period for me. Whereas 9 months sounds like most of a year, and I would be compelled to try for 12!
