I woke my boyfriend up the other night to ask him who a contact in our cell phone was, the name was jaime,?

So when I asked who jamie was his response was "she told me she would be a good person to have sex with" I asked 2 more times and got the same response, I flew off the handle,after I flew off the handle he said jamie was a guy he was going to do work for,that part appears true but question I have is why would he answer with "she told me she would be a good person to have sex with?
