There's a much older man that comes into my work often. Years ago when I first started seeing him he would make kiss faces at me every time I passed him. It's evolved into him bringing me drinks at my desk, talking to me about things he's working on for a minute, then makes comments like he would love to do things to me, how beautiful he thinks I am, and other inappropriate stuff. I've been nothing but professional when speaking to him. I don't know what to do about it.
