Can someone clarify for me how this forum works? Do I set my own challenge for 30 days and post progress or does someone else set up a challenge and whoever wants to join posts progress?

hey guys I used to be quite active on the subreddit but took a break for a while. However I am bit confused about this site. Can anyone point me in the direction where it's talked about sexual strategies? I don't care much about social issues, I just want to talk about fucking bitches.
