Why does sex have to be in EVERYTHING?

For once, I’d like to be able to listen to a good book without listening to hard-core porn!

This is a book about a guy trying to avenge his family, that has to build a team in order to go on a mission in exchange for a lead, sex, taking on genetically modified dinosaurs. He kills a bunch of bad guys, uncovers yet another sick government cover up, and then finds out that one of his team has more backstory than he thought. Why this needs a sex scene and innuendo throughout, is beyond me.
