During the early part of our experimenting with Karezza, we spent more time close to the edge, and experimented with different positions which frequently spilled me/us over into orgasm. I'd say we managed to avoid orgasm more than 1/2 the time, but trying to have Karezza 2 or three times a week tripled the number of orgasms we were having compared to the previous year, where we had self-regulated by only have sex one or two times a month most of the time. So we were having lots more orgasms than before. This wasn't so bad, but it wasn't our intent, and we soon learned what our triggers were, and what to avoid.
Now that we're 18 weeks into this experiment, we've both gotten better at avoiding orgasm, but it still sometimes happened when neither of us is intending it, or even feeling very aroused. Scissors is the only position that's relatively 'safe', in that it isn't very arousing, in and of it's self. We've found that we can't do any face-to-face positions without "dangerous" levels of arousal for me, which has really been disappointing, but it is what it is. So sticking to only the scissors position, and limiting the amount of time to 15 or 20 minutes, we've been able to avoid orgasm for the last month, entirely for me, but at least twice during this time, my partner has had an unintentional orgasm.
So, here are my questions: for those of you who have been doing this longer than our 18 weeks - and who are still having 'inadvertent' orgasms, what would you say is the frequency of them, and when it does happen, do you both orgasm? Either way, do you go back to your usual Karezza schedule, or do you abstain for a longer period to get past the hangover period?
