When sexting goes wrong? So i've been friends with this girl for about 8 months or so, I've never even met her in person, I know her through a mutual friend. And yes we are local to each other. So last week i asked her if she had any naughty pictures or something like that, and she opened up, I started talking to her differently, letting her know I was interested in her. She sent me a naughty pic, A few days later she sent me a pic of her ass. 

Just a few days ago, I sent her a few pics of me standing in a mirror with clothes on showing my boxers with a bulge. Since then she has pretty much been ignoring me and acting strange. 

Before I just cast her to the wayside, I am curious what are the possible reasons for this? The big one im thinking is im just not attractive to her, but she KNEW what i looked like, and I honestly think I look good for a guy my size.

TLDR: I sent a pic and suddenly the girl starts acting weird and doesnt return my texts that involve said picture.
