Need advice

So I been messaging this guy for a few days. He always tells me all Im good for is fucking and he owns my holes. He can fuck me whenever and however he wants. He told me to never delete or block him. I like to feel good and be controlled but I feel like this isn’t good way. It doesn’t seem like he cares about anything except sex. He wants me to touch myself while I’m at work in the bathroom. I would think shouldn’t really be doing sexual stuff at work.
