What are the chances my boyfriend is cheating on me?

We live together and are only separated when he is at work. We are constantly communicating and even track one another’s locations so I know he’s physically at work. Please don’t give me crap about the location thing please. I’m working on that. Could it be possible that he’s cheating at work with someone from work? He doesn’t wear cologne but comes home with a strong perfume smell many days. He has an automotive job and is in customer’s vehicles and also close to technicians who he goes on test drives with.
