Insane! I'm a regular contributor to IAFD to try and get some of those numbers up. There are scenes from sites that still aren't listed on there. They don't accept OF scenes anymore though.
I've heard a lot of these girls have fucked so much porn dick that it's hard for them to go back to regular guys. They get spoiled, and most guys don't want to date them because of all the dick they've sucked/fucked, Nicole Aniston talked about it on an IG Q&A recently. Someone asked her what her body count was, and she just said "A LOT" lol.
