Not to put the blame (sic?) on the lady, but in my case, her attitude when we first get together is a major contributor to how the lil' guy does that day. (See essence post #9 above)
There is nothing worse than walking into a room with a lady, and with her back to you says, "go ahead and get your clothes off and put the envelope over there" or something of that sort. It amazes me how a lady can set the tone of the hour in the first few moments of the encounter.
