If I can add to the discussion, in Islam when something is not specifically mentioned historically and is said to be connected to a Prophet, we are asked to not speculate, think about, comment or infer anything that cannot be verified with accuracy.
As Prophets are the models of perfection, it is beyond doubt that those attributes attached to piousness such as faithfulness to God, chastity, honesty, sincerity and the like are suited and firmly grounded in the life and qualities of these great figures. Anything outside of or opposed to godliness is diametrically impossible to see, think about, reflect and believe could exist with a Prophet. This is the teaching of Islam.
Second, where themes like the marriage of a Prophet to someone else namely Mary Magdalene, the much spoken of migration of Jesus and his family to Egypt in his childhood and other such stories are not mentioned in the Qur'an for a reason. Allah has not deemed it as important for us to be concerned with in contrast to the message that Jesus and other Prophets actually brought and taught, namely what Our Creator wants for us, how to achieve them and the implementation of Divine guidance.
What Allah has not told us now, we may be given answers in the afterlife and as someone has already said, responses by those directly involved, namely Jesus himself, may be forthcoming when the time and circumstances are ripe, relevant and responsible to receive them.
