why would'n God want Jesus, the man,to be physically,mentally, etc. fruitful and mutiple on earth as in heavn

huh?
I can tell you the Gospel of Mary thing is what leaders of the early church would call heresy. It hasn't been accepted by knowledgable scholars (Biblical and otherwise) throughout the centuries. I'm telling you this dispassionately and as I've respected your opinion, I hope you'll consider mine. The very Bible itself states that there is nothing comparable to marriage in Heaven as there is on Earth. When looking at Creation, bring yourself to its root: purpose. God created woman to help man, once expelled from the Garden, they were told to multiply (looking ahead to producing eventual redemption through Jesus). Saying that Jesus married wouldn't necessarily be (and again, I'm saying this dispassionately) sinful, but it would go against his purpose and just be pointless as his mission on Earth was to be born in order to die for our sins and rise again, defeating Death. Also, Paul writes in Phillipians, I believe, that marriage is great and a wonderful gift, but if you can be single and dedicate your life wholly to God, then that is probably better (this is again in light of a greater purpose and in the scope of eternity). Not that there's anything wrong with marriage and sex within marriage-it's great.
However, Jesus never married.
Hope this helps.
