Friends with benefits with ex

Me and my ex broke up a few days ago and realised that neither of us are ready for a relationship (we were together 6 months but were extremely close) he was persistent he wanted to be friends with me as we still care about eachother so we decided we will still meet up and talk about things with eachother but we also said that instead of us having to sleep with random people we would rather sleep with eachother it we need to . We are both happy with the arrange my. I just want to know if anyone else has had an experience with this and how did it go??
