I'm thinking of my girlfriend and I trying to come up with safe-words for the bedroom
Why are you considering using safe words?
We're going to experiment and want to make sure nobody gets hurt by accident
That's a smart idea!  Safe words help prevent harm during potentially dangerous sexual activities, which is a good thing.  I hope you two enjoy yourselves!
Thanks! We are excited to branch out into something new.
It's good to spice up your sex life as long as your responsible about it. You'll get more out of being intimate with each other while being on the same page. This will create an overall healthier relationship.
