I am a dirty old man
I am 50yo male. I was at my mothers house and we were looking at family photos from when I was a kid in the 1970s. There were photos of me as a teen in really short shorts and also of my sister one year younger than me in little short mini skirts and dresses and some with her undies flashing. I got sort of turned on in a weird way. Thought about it a few times since. I guess I am a dirty old man.
