What makes you nervous?

I am not by nature a nervous sort of person but I suffer from retrospective  nervousness when I hear that something I have been involved with has not gone to plan. I question myself as to whether I had done my best in that situation, done what was required of me and done anything extra that would have smoothed the wheels of a positive outcome. I wonder if that is a normal reaction. I would say I am a fairly confident person but not supremely  confident. As a woman I am without balls, both real and metaphorical. Here lies the pondering part of this ponder. I have often wondered what it would be like to try out some testosterone for about a week. Nothing whatsoever sexual in this,just a week of being in someone elses size 10 boots being male about everyday things . Goodness I know so many absolutely lovely men who are just a pleasure to know. But in life I have met some absolute corkers of bad examples of malehood, men who I really struggle to empathise with or understand at any level. Would a week with testosterone give me any level of understanding or insight?

The reason this question prompted this quite random ponder is that some men would not bother to consider that anything they had done would contribute to a less-than-positive outcome.  Cocksure springs to mind.

There is no female version.

Quim Questioning has a nice ring to it.

” The Marquee blew over the sea wall,   he was somewhat Cocksure that everything had been done correctly”

” The Marquee blew over the sea wall, she immediately Quimquestioned if everything had been secured correctly”

A week of feeling cocksure might be quite revelatory, no retrospective nervousness.
