"Could have started a perfect race..." This is comic book level speculation. The Watchtower is grasping and getting away with it because in one hand they are holding a big cartoon mallet behind their back while with the other they hand out this kind of "spiritual food in due season". If anybody chokes or refuses to swallow, WHAM!
Since a huge chunk ( teens through 20's) of Jesus of Nazareths life is summed up by nothing more than saying "he was a carpenter", then who knows whether he was a virgin or not when he was executed in his early thirties. He may have had children or at least lost his virginity. It makes more sense that he did than that he sawed and hammered every day except the sabbath when he went to synagogue and had zero normal life otherwise.
If he was anything like young hardworking carpenters of today he had a hot girlfriend, a badass pick up truck and a bass boat stocked with cold beer.
