Aside from here I don't put any pics of myself dressed "as a girl" anywhere. I'm not worried about people I know seeing them because if they do that means they came here. Which means they are into the same thing.
Why do I take them? *shrug* To see how I look I guess.
As for how I take them, I usually just set my phone somewhere and use voice commands to take the picture. Either that of I use my laptop camera on a timer.
