About the Sexualitree

The Sexualitree is a way to see how we experience sexuality in different ways. Sexuality affects us on different levels of our lives, and each person uniquely. That said, we understand folks who land on this website will have questions. Let’s start with the Ws (and an H).

What is this?

The Sexualitree is a model that can help us see the different ways we experience (or don’t experience) sexuality. It offers a platform and a format for conversations about sexuality that are complex and accessible. It’s available in a variety of formats, and we invite you to use in whatever ways you see fit — we hope it helps you.


We hope to bring a new toy to the sexuality education model playground, and we hope you find it useful. The existing models of comprehensive sexuality are often taught as static & constant, rather than as an evolving concept that stretches and contracts and grows differently for different people, so we wanted to add something that embodied the growth, change, and organic experience that is many folks’ sexuality.

Who’s it for?

Everyone! (You and you and you and YOU!) We’re all sexual beings, whether we have sex or not, and coming to an understanding of what that means to us personally is an important part of being a thoughtful human. While some folks have a more direct or formal role in educating others about sexuality, we hope that everyone — from sex educators, to teachers, to parents, to preachers — who finds this model can find it beneficial.

Who made it?

Sam Killermann, and Karen Rayne. You can read more about us individually through those links, but what we have in common is that we’re sexuality educators, we live in Austin, and — you know what, this list is long. Just know that we both want to do what we can to help you talk about sexuality in a way that is inviting, free of shame and stigma, and helps folks better understand themselves and others.

How can I use it?

However you’d like. We made this for you to teach, print, project, improve, edit, revise, and — above all — use. So use it. Let us know how you’re using it, if you’d like. And how you think we might be able to improve it (which we’d like). But seriously: you can use it to do good in whatever way that was passing through your mind as you read the heading to this paragraph. And, really, please do.
