So you’re having great sex—great! It’s an integral part of a healthy relationship. However, if you just hop in the sack anytime you run out of things to talk about, or get in an argument, or see each other…you’ll weaken your abilities to entertain one another out of the sack. And the truth is, there will be many times one or both of you can’t have sex. Perhaps one of you gets sick, or tragedy strikes you and you lose your libido, or the cardio-activity becomes dangerous for one of you.
