It would not be an ideal situation for a child to be raised by a single man, any more than by a single woman. It would very much depend on the man and the circuмstances. I know of a single missionary woman doctor who adopted two children, siblings one of whom was disabled.
But the way OP has expressed it
does not feel called to the married state but want the joys of parenthood by himself for himself and for care in old age..
I would say definitely not.
Nobody has a right to parenthood especially for the stated reasons.
There are great saints who made their life work the care of abandoned children, for the Love of God, not for selfish reasons.
