I appreciate the non combative tone of your comment, and seemingly good faith engagement.
I do agree that it's ok and normal to make fun of bodies. I just think we should generally keep that related to our own bodies and our own experiences though, and I believe I indicated as much in my original comment.
If this was "I wish I had this when I returned to the office after giving birth" that would not be a problem at all in my opinion. My issue is the normalization of talking about others bodies. In this example it feels particularly unneeded as it is related to a somewhat intimate situation.
Obviously people are welcome to disagree with where the line should be drawn, but I think these comments should generally stop where your personal body does.
