Tumblr banned porn content on their network in December 2018, but there are lot more sites where you can share your porn thoughts, interests and to get pics and videos of great tits. I don't know how much girls are sharing their porn interests, but men certainly do and actually, I got a lot of links from friends, from which I then launched this website. It's fun to discuss, share or just connect with people who enjoy the same stuff. Everyone I know is regularly visiting one more social networks.
