Do you tell everyone every time you have sex with your husband? Do you tell everyone every time you have you have a pap smear?
There is a such thing as privacy. Wanting something to remain private isn't the same thing as it being a bad thing.
Do you shut the stall door when you use the restroom? Why? Are you ashamed?
Of course. And even the most simplistic among us will reocgnize the difference between a desire for privacy and a sense of shame.
I have sex with my wife. While I don't announce it each morning I am not ashamed of the fact. My children are testimony to the truth of this.
I once had a co-worker who announced his plans to go home for a "nooner" with his wife, since the time when the children were at school was the only time when the two of them felt truly free. He acted like he was getting ready for his marriage. The office took it well, with a modest amount of good-natured ribbing which he enjoyed. While I am more private than he, there was no shame involved because there was nothing to be ashamed of.
I have never heard anyone say they were planning to spend quality time with Rosie Palm and a porn movie. If you are arguing that nobody should feel ashamed of such plans, that is one argument. If you are arguing that the shame should not stop them, I would disagree with you.
A sense of shame is a good thing. Allowing it to dictate our actions is also a good thing.
Shalom.
