Yes, of course. I have them on my phone, have sent them to people, have them online in a couple places, etc. I have nudes of my partner too, but those wouldn’t qualify as selfies obviously.
Laying about? Surely not; they’re all safely locked away in cloud storage.
It’s times like this that I suddenly remember that I have the “Cloud to Butt” Chrome extension installed… It has never seemed more appropriate. 
No nude photos here.
I figure if some were taken without my knowledge, then ultimately that’s the other person’s problem, considering that as an adult, I’ve always been some degree of fat and hairy.
