How do I ask a coworker to hook up?

I have a coworker I’ve worked with about a year. We also go to college together. I’m about 2 years older.

I don’t want to date him, but I so badly wanna hook up, he’s just, you know, so hot!!!

I do I ask in a way that

A) won’t make this awkward and

B) won’t end in me being reported to HR

I really have no interest in dating him, he’s a good guy but I’m not interested in dating. One of my guy friends said “Tell him you think he’s hot and ask for his snap” but that most certainly won’t work.

I’m not ugly either, I’m pretty attractive, I just get awkward cute guys haha
