As someone who has freshly immersed themselves in the community of Substack, let me be the one to say that it is passing the point of irrelevancy. If you don’t know what Substack is, you have a lot of catching up to do. Substack is an online platform for bloggers, creators, and onlookers alike. The appeal of the site is different from other social media platforms, since it focuses more on direct audience engagement. All in all, you’ll be able to find a little something for your niche interest — and that includes sex-ed Substacks.
A topic that has garnered significant attention is sex and relationships. Even more so, the importance of sex education. Sex education is highly important for young adults, as it provides them with knowledge on making healthy decisions around sexual health and developing a positive mindset towards human sexuality.
If you haven’t had any sex-ed courses offered in middle or high school, the internet can be a pretty useful tool for education. According to Her Campus’s 2025 Sex Survey, 76% of respondents said that they use the internet as a source of sexual education. So if you are at a stage in your life where you may need more guidance on sex or sexuality, these six Substacks will be best for your bookmark section.
In all of these Substacks, the importance of sex education serves as the main frame with no guilt at all. So, if you want to read on and become more sexually knowledged, you’ve come to the right place.
