We've been off the karezza wagon, and it's no good. Irritability is up. Seeing each other's beautiful true essence is down.
Incidentally, we had got going last year with karezza and made good progress during a period when I was not cycling, due to breastfeeding. With the return to a monthly fertility cycle, it seems lizardly havoc broke loose. I would say it's all on his side, but I'm sure without realizing it, I'm contributing to the heat.
When I come, my perception of him really changes. I become less content, less generous...
My guess is that if you get too near the edge, and don't calm things down together, this could hold true for karezza as well. I wish researchers were investigating all the options better.
In karezza, the sex doesn't end in orgasm. But that doesn't mean it's anti-climactic.
