She needs to meet the OP's boyfriend from yesterday who stops in the middle for donuts.

Haha step your game up, lame ass

Give her that safe word, but then abuse it. Any time she's complaining about something or talking to you about something you don't care about, you'll know what to say.

Rule 1: If a woman is not able or willing to communicate her wants and desires to her partner you deserve all the shitty and boring sex she gets. Rule 2: If a man is not able or willing to communicate his wants and desires then he deserves all the shitty and boring sex he gets. It can be something as simple as 'a little to the left' to as difficult as 'I'll only sex up someone who's a naturally bald one-toothed midget'. If you don't put yourself out there and communicate it, you'll probably never ever get it.

her "caramel! caramel!" you "are you hurt?" her "No the walking dead is on!"

Did she tell you it was for when she gets bored or did you figure it out? Cause I feel as if you figured it out you should have tried to change things up.

Since when did you begin doing BDSM? Since 50Shades? pffft.. fail!

"I wanna know what love isssss, I want you to show meeeee" if none of these work time to belt out a safe song, OP. Right to the point.

Maybe you should get into BDSM

By looking at your user name "username" i would suggest the safe word to "use her name"
