Hello. Sissygasms work as they should, however, some things don't count if you've unlocked the Mind Wrecker skill. That's all. This shouldn't affect your progress. I wrote about it in the latest devlog. Where exactly are you not making progress? Maybe there are some other bugs.

After having sex and checking the progress of the sissygasms during, I've gotten up to 14 but when I quit and it loads the statistics afterwards it always says Sissygasm - 0. Even before unlocking the first level of Mind Wrecker it wasn't counting them. The only thing that has raised was the Anal Endurance. Should I delete and redownload maybe?
Edit: It's also entirely possible it's the app that has caused the issue. I'm gonna try re-downloading from the browser website. That has helped me in the past. Sorry to bug you.
No, ignore the Sex Results, they don't display everything that was counted during sex. It's a known issue, and I wrote about that as well. If you go to your sissy's stats->statistics, you'll see that sissygasms do count. Also, you can see that your sissy's Sissygasm stat is slowly increasing (stats -> sex stats).
Edit: You described the known bugs. I don't think re-downloading will fix them, but they're being fixed in the next update. I'm working on it right now. Don't be sorry, feel free to contact me if you have any questions.
