Woah I was amazed how hard it is to relapse even with my non dominant hand! It's like I had an ED to myself, I was watching probably the hottest scene in my life in porn but it was a whole different experience with my left hand. I got aroused slower and harder, the hand got tired faster. So yeah, back to 0 but I have proven to myself how porn desentesizes me even to myself once more.
This cracked me up at first but later I realized you may have made a profound observation so I gave it some thought. I guess what your sayin is that the nervous systems of PMO addicts is so strongly hardwired to only respond to the routine method of stimulation that even a switch of hands does not do the trick. You can also interpret the effect to mean that your left hand is not trained properly or that it was just not meant to be. Most people write much better with their dominant hand because the other does not have sufficient practice or maybe ambidextrousity is related to gene expression due to the hormonal exposure in the womb or some other molecular biology or genetics funda. Also, just because many women find it difficult to O while having penetrative sex does not mean they are addicted to alternate forms of stimulation. It may just not be the technique that works for them and either their partner may need a bit of training to hit the spot or they eventually acquire a taste for the alien technique. So either you train your left hand how to do it right or you train yourself to start enjoying what your getting out of your left hand. I'm in no way encouraging you to relapse again. Just saying hypothetically.
