How to get an ex co-worker to sleep with you?

This sounds kind of weird but I feel sexually attracted to one of my co-workers at the work place. I think he is also interested at some level having judged his glances and flirty attitude towards me. However he is also very dedicated to work and when I quit he was sick, so we never got to talk properly. Last time we talked I asked him how he was. We haven’t talked since but I’m still thinking about him. Since I quit, I was thinking whether he would be interested in any kind of relationship with me? What’s the way to go about it? O have his number.
