Need advice on my coworker that’s 12 years older than me

Hello to all the men out there. I need some advice. I am ridiculously attracted to one of my coworkers but he’s 12 years older than me. I’m in my mid 20s and he’s mid 30s. I wanna ask him to hookup, nothing serious, but I have no idea how to even broach that subject. Would an older guy even be interested in the idea of this? Also I’m not too worried about the whole working together thing since I’ve already been looking for new jobs. It would definitely be awkward if I got shot down for a little bit but I’m leaving eventually so I’m not super worried about that.
