Dick pics🤔

Courtney
Basically, I got a snapchat from this guy.. (We have been talking for about a year) and he randomly sent me a dick pic.. I wasn't shocked, as he has sent them before, I just wasn't in the mood for anything like that, so I didn't reply..
Now he has the audacity to be mad at me because I didn't reply to his dick pic, like wtf. 
Can someone please explain wtf I've done wrong cause personally, I don't think I have done anything 😂😂😂
