Am I overreacting?

My BF text me saying " I don't any that are appropriate" Then text me saying oh my bad wrong person. My first reaction is okay who's asking for you to send them pics? I mean you he has plenty on FB.... I'm just confused.... And then he posted on snapchat " when you send the wrong person a text😂" I don't find anything funny .
