Non-monogamous folks talk about the importance of having safer sex alot, but there don't seem to have too many discussions about what it is, how to have it, and what happens when things go wrong anyway.Plus, there seems to be this ideal that safer sex is just about preventing STIs. (And sometimes pregnancy.) Safety in sex is a whole lot more than that. It's injuries, and trauma, and consent, and having some important discussions with other people, and making real choices about what risks you will and won't take, and... well, enough to fill a book.So I did.As usual in these books, I don't offer much in the way of answers. You need to do you. What I offer is a lot of information and some questions to help you figure out what you want to do with that information.
