I (25 f) have created audio recordings of me having sex for years now.

That's it. I have never told my partners, so basically nobody in my life knows this. It's only audio, nothing more (anything beyond that would not be morally ok for me) Why I don't feel bad about it : nobody got hurt in the process and the audios aren't used for anything bad. It's just a nice memory to have from the person I was with, in my opinion.

Go on, roast me, I deserve it.
