Sex with your EX 😳

Good evening ladies! So here is a topic .. Have you guys ever had sex with your ex after being broken up for a long while. Post your  Experiences.. Did you reconnect , did you feel guilty, did not feel the same ? The back story to my post lol so I've been single for a little over a year and haven't found a guy I feel comfortable having sex with sooo I was thinking maybe my ex? I have no feelings for him anymore I want it to be like casual sex.
