A co worker of mine and me kissed one day a months ago. Everyday at work we go off and makeout. We talk everyday he says how much he wants me but we have never had sex. He obviously gets turned on and he seems to care about me. So what gives? Why dont we do it?

or perhaps he's afraid of getting fired for making out on the job
after all unless you're in the adult industry you're not being paid to get laid at work. or even make out.
in fact if your company has a "no dating" policy... perhaps he's afraid of getting caught
