No.  A priest's job isn't to nose around in people's personal lives.  It is his job to provide counsel if they ask him to.  The fact that some priests apparently have the time to nose around in people's private matters suggests that they really need something to keep them busy.  Perhaps if they are so bored, they could spend their time doing something worthwhile like visiting the sick in the hospitals, starting a soup kitchen, counselling troubled youth, working on gang violence, volunteering on a committee to deal with racism, dialoguing with other religious leaders, etc. 

And children should never be denied baptism because of their parents' sex lives.
