Hi Chris18,
I have answered the poll, and was going to before, but wasn't sure I'd vote a Y or N.
However, having lived with POIS for 40 years (had since teens), I do know that when I was younger, it would have been a definite yes to your poll.
Even now, although an "O" is what really brings on my symptoms, there is - I also wholeheartedly believe - some neurological activity at play that influences us emotionally, physically and psychologically in a way that screws up what should be, with obvious boundaries, a pleasurable experience with our life partner or our good selves, whether we have an "O" or not as you describe.
Obviously, over 40 years, I have literally tried everything, and found nothing that helps any better than avoidance of what younger guys certainly can't avoid.
Hang on in there, be gentle on yourself, we're all hopeful of what the research WILL be a positive springboard for. :-) Sometimes, what we focus on grows as a problem, in my experience, so do try not to focus on something that you are NOT causing.
