The last time I tried Karezza with my wife was last summer over the period if a few weeks. About 16 days in on one stretch, I unintentionally went over "the point of no return". I was basically still when this started to happen. What should I do at this point? Stay still? Withdraw? Thrust? We never quite got back on the horse after that. We may try again soon. I am on Day 15, no O. I don't want it to happen again, but it may.
