Sex with an ex

Ladies I don’t want any judgment this is my decision I’m just looking for advice, me and my ex partner didn’t work out because I never wanted sex I just wasn’t ready so we split up no other reason we really did love eachother but understandable on his behalf he’s a man he needs sex and as you do I moved on from him and started sleeping with someone else and it just felt right because I was ready it didn’t hurt there was no pressure and now I enjoy sex, my ex has got back in touch wanting to meet me and I really want to sleep with him now I’m confident and no longer a virgin, do you think it will go in smoothly and we’ll have great sex or do you think because it didn’t work the first time it won’t work now? Although I’m not longer a virgin, maybe it was him...but I am attracted to him idk
