I think that what goes on internet stays on internet so once you posted something it’s there forever. Because of that (and my introvert nature) I don’t post much on internet to start with and when it comes to pictures I don’t have selfies of my male self (taken one in my life so far, for a photo id at work).
I do have a personal restricted album of a ton of Kelly selfies that I only share with my wife and daughter and while it is “in the cloud” (AKA some one elses computer) I’m not to worried about it.
I have considered posting selfie pics of me here on CDH and major reason I don’t is that I’m a lady with max 5 pics so I leave that for now.
I’m not afraid that any of my friends/family would recognise my CDH pic (they probably would) because if they do it also means they are here and why would they be here on CDH?, maybe that person is a closet CD also just like me.
