sexting

I am a texting fool, I love it.
Perfect form of communication, especially since I hate talking on the phone.

I have been emailing, IMing and sexting with a guy i'll call Mr.Tush.
We talked about the dirty things we like to do.
This was early in our relationship and we hadn't sent any naughty pix to one another.
So Mr.Tush asks for a pic of my panties.
I go to the restroom, slip them off, lie them on the sink and snap a pic.
I slip them back on and return to my desk.
In my phone I have the numbers of 2 guys with the same first name, Mr.Tush and a friend of my ex.
I pull up the pic, send it to the first guy with the same first name.
Guess what?
It was the wrong one.
About 30 minutes later I realize this when i get a pic of his junk!!
This friend of my ex sent me a pic of his cock - geez.
Now he thinks I want him.
How do I get myself in these situations?
