I had the urge to wear my friends skirt, I ended up doing it without her permission.
Why would you do that? You shouldn't take people's belongings without their permission.
I wanted to feel sexy. I ended up taking a nude photo and sending it to her friends.
You wore an article of clothing that wasn't yours and sent nude photos as well. This all seems like a sexual perversion to me.
It's just a skirt, I couldn't find any pants. Oh well.
Regardless if it's just a skirt or not you took it without permission. And to add onto that you sent unsolicited nude photos the people. This is wrong and you need to stop doing this before you lose your friend and potentially get in trouble for sending the photos.
