Come on guys, you can't just start sexting out of the blue like that. You gotta work it into the conversation.
I know everyone's relationship with their spouse is different, and my wife generally gets the joke when I call her the dishwasher. If she asked me if I ran the dishwasher this morning, my response would have been along the lines of "I was kinda hoping to ram the dishwasher tonight"
Speak for yourself.
Texting, "Hey baby, How are u? I'm horny!", has never let me down.
