I do performance sports with my dogs and have taken opportunities to do workshops and training for the canine athlete. Overwhelmingly the participants have intact animals. This theory that an intact dog is more aggressive is not borne out by many studies that have looked at it. In fact and not surprisingly the dog to dog aggression we have experienced usually (but not always) comes from neutered or spayed dogs. I also think aggression is more breed specific than their s or n status.
I don;t think you got lucky I just think this is normal, My males intact do not mark in the house even when my female is in heat. Although it is not pleasant when my female goes into heat. And requires a huge amount of time and supervision to avoid unplanned matings. I would NOT recommend this for the average pet owner. That being keeping intact both male and female dogs in the house.
I think that if you want to neuter him you can and couple the operation with a dental For a Yorkie I would be more worried about dental disease than any rare form of cancer from having an intact male.
