Well, yes, for me it has been as clear as crystal for a long time - POIS causes me, among other things, a drastic and sudden change in personality, so social life and relationship have been a great challenge for me. Well, now, in the last couple of years, with better control over my POIS symptoms and abstaining more often than not, I am more stable on the emotional side. Moreover, now that I am over 50, sexuality does not matter as much as before in my long time relationship, and my spouse definitively prefers to have me staying calm and kind, so she, like me, prefers to keep our sexual activities at a very low frequency - I think she had more than enough of the "anxious and exhausted madman" episodes ! And me too ! What's great for me, for us, is that she really loves who I am when I am not in POIS, so she had stayed with me all those years, despite my inexplicable emotional instability. But now that I have gain some more control on my symptoms, she has adjusted her expectations the new situation, so she wouldn't accept the kind of full-blast POIS attack I used to have. So we are very cautious not to awaken the POIS monster.
My 9 years of psychotherapy are for sure also a factor and my emotional stabilization process.... Yoga, meditation, regular exercise, and healthy diet, too. I am attacking from every possible direction this multi-headed POIS monster !
