I can see the "Big" picture now..
It was me! Having read the Kama Sutra at 17 and realizes that my happiness is the product of my sexual partner's happiness "first", I have been pushing myself in life to be critical of my own performances - on and off the bed.
Until one can benchmark themselves or others and get feed back for setting goals for objectives, there can be no improvements.
However, Improvement is not for everyone! Some are shy, some don't care, some have fragile egos. As they say, it is not everyone's cup of tea.
James T Kirk, I hope this answers your question.
For most men, there should be no fear of their identities being exposed in front of their friends through the reviews unless it was very "explicit" like - He has a scar 2 inches on the lower back (that's James Bond!).
I sincerely thank all who contributed so far. I think that some SP are willing to help (in one way or another) but sometimes we just simply run out of time for a de-briefing afterwards hence the suggestion for SP reviews.
In summary, I feel that I am in the minority but not an extinct creature as yet!
