I'm not really broadcasting it, and for many, I am just saying that it's hiatal hernia repair (which it also is). For some, I will tell them that while they're in there, they're sleeving me too.
I guess in the end, I'm not entirely sure why I'm not talking about it more. Some feels like to avoid uninvited opinions and comments, some because it's not really anyone's business but mine.
My wife and kids know, and my sister-in-law (who's had a BPD-DS, very successful), and my partner at work knows, but I don't know whether or when I will tell any others.
