I'm sure this will sound like a jerk BF...But evidently you are OK with those questions to avoid a ticket, because you answered them and avoided the ticket.
The cop was just verifying that your story was legit with the questions. Either that or he's going to stalk you now until you become his gay lover. But I bet he was just verifying your story.
He may have been a jerk, but that's no surprise. Some cops are jerks.
