Parerents are perfectly capable of loving their children but not each other and gay people can and do want to have children. In fact for someone of Danny Zuko's generation getting married could be seen as the only way of getting the family he obviously wants and loves. Gay adoption or a single man adopting a child has ony very recently got acceptance.
Th most recent child was conceived out of the grief of losing their oldest.
The problem or these two is CoS not tht he might be gay.
wasn't there a blind item on here a good while back, that indicated that she had used his tadpoles that were left over from a previous conception
and he didn't know anything about it, in fact he was looking for a way out of the marriage at that time...... sure I read that blind on here....
