Napoleon & Carol
"It might mean you might not want to be exclusive with someone. Now sex doesn't mean exclusivity, but it does complicate things unless you've talked it out beforehand. Until you're on the same page, I wouldn't try having sex with anyone, regardless of whether it was casual or exclusive." He had a few firm rules and one was that he didn't get between the sheets with anyone unless they both knew what they were getting into.
"It could also mean that they're not sure about whether they want to continue the relationship or not, and not having sex makes for a cleaner break if they decide to not continue forward. It could lend to why it's casual, but honestly? It could be anything. You'd have to talk to the person involved to get a better idea," Napoleon said, smiling gently at her. "It's better than asking someone who doesn't have the same intimate knowledge the man in question might."
