Here is a list of Adults-Only Sexy Geek Conventions, now Worldwide!
- 18+ geek conventions that don’t welcome spicy content will not be listed.
- 18+ mainstream porn or fetish cons will also not be listed, like Exxxotica Expo or AVN Expo
- All-ages geek cons that simply allow adult content will not be listed (sorry, NDK & CONvergence)
- Conventions without their own website will not be listed. Event listings on Social Media don’t count.
- While 18+ Furry Cons are fun, they’d dominate this list, so check Fancons.com for listings.
- This list will be updated with new information as it becomes available.
- Feel free to contact me if you see I missed one.
- Thanx to Fine Fictional Men for their international listings.
