My partner were talking about the last 4 months of our experiment and the last year or so in general, and analyzing the data I'd recorded.
He doesn't notice a hangover, but he doesn't miss the orgasms and he can see that I'm happier, so he's happier. I'm not just happier, I'm calmer, more resilient, thankful that I'm so lucky to be so blessed with my partner and many times, just plain blissful. I'm also sleeping better. My blood pressure is lower.
Because we're engaging physically more often, the time has to come from somewhere, and the time trade off has been less TV time for him, for me, it's been reading time. As far as outward manifestations, friends have commented (I never imagined that anyone else would notice) that we seem much calmer and happier, and they wanted to know what our secret to staying happy was.
From my data, we've changed four things -
1. We're having PIV sex 4 to 5 times more often now than in the last year.
2. We're engaging in extended bonding behaviors every day, which we were not doing for the same amount of time each day during the pre-Karezza period. (We work in the same department, and interact in our work on a daily basis, commute together, and take lunch together every day. We usually cook dinner together each evening, but we always eat together.)
3. We are not intentionally going for orgasm. When orgasms occurred, they were unintentional. The effect of this is that the amount of time we spend in PIV intercourse is much greater than in the pre-Karezza period. (Probably on the order of 10 to 15+ times longer, in total given the increase in frequency.)
4. Both of us have had 2-3 times as many orgasms in the most recent 4 months than we did in the prior 4 months.
Given that we've had many more orgasms than before, we were puzzled, as we should be more hung over, more horny and more irritable than during the 'control' period, but in fact, we were not. The few times we have been noticeably horny we got really 'overheated', but didn't orgasm. So, I have to look towards the benefits of extended gentle intercourse, and the consciously applied bonding behaviors as the major catalysts in our increased levels of love, connection, and happiness.
To me, this speaks to the benefit of everyone applying the practice of daily bonding behaviors and even part-time Karezza to any relationship. Even if you can't manage to avoid orgasm every time or even most of the time, just keep trying. It's still beneficial.
