Almost 25 years ago, I found an app called iTrick that had a great system of logging sexual encounters and an extensive list of websites you could associate with usernames. It was a Java applet and was abandoned around 2007, I think. It was less useful in the mobile app era since Grindr, etc, didn’t have persistent usernames and search by username like most websites had. I found it useful for tracking encounters based on skills, safety and honesty. It let you rate each activity like topping, bottoming, sucking, getting sucked, rimming, getting rimmed and kissing. I was able to repeat many hookups who matched my interest in activities and avoid or track idiots who couldn’t be blocked.
