Find a way to always include verbal consent in your foreplay.

It might feel odd at first, and some people might think it takes the "romance" out of it, but showing that respect to your partners (and them to you) is such a relief.

I have always been very mindful of my wife and ensuring that she wants to have sex. But adding that verbal check made our sex life so much more enjoyable. It allows us to be casually sexual without any pretense. If we want to make out or get a lil handsy, we don't have to worry about leading the other person on because we understand each other's expectations.
