I want to have sex with my friend but we're part of a church group which I'm in charge of

A little bit of background so I had this boyfriend and I ended up having sex with him then a while later he broke up with me. As I was going through all this I messaged the guy to talk about it all because he's a good listener. One day he messaged me that he needs to get laid turns out that was an accident I told it's cool because I havr friends you actually text me that too. (I really do). And then we started talking and I ended up telling him that I had sex with my ex. Even since then (and before my ex broke up with me) I've found him very attractive mentally and physically. After that conversation I've been noticing him talking to me more, hanging out me more, and staring at me more. I don't know what to do about all this. I probably won't get a chance to have sex or a relationship with him anyways but I just wanted to tell someone all of this.
