Dating and sex can feel like they come with a hidden rulebook. You’re meant to be adventurous but not too adventurous, confident but not reckless, and always somehow immune to consequences. So the potential of catching an STI – whether it’s a scare, a diagnosis, or a message from a clinic – can feel not only a health impact, but also a judgement on our character.
In this episode, we’re unpacking the psychology of STIs in our 20s why they carry so much shame, how stigma shapes the stories we tell ourselves, and what it looks like to navigate disclosure with self-respect.
We explore:
• How common STIs really are
• The most common infections in our 20s
• The difference between treatable and manageable
• The role of sexual shame and purity culture
• How shame drives secrecy and avoidance
• When and how to tell a partner, and what to do if you face rejection
If you’ve ever felt panicked, embarrassed, or stuck in your head about sexual health, this episode is for you.
