young kids grow up in a one parent household where their mom is sleeping around and think that is how it is done and do the same thing when they get older.
It is much more common for a child who has been raised by two parents for them to be in a stable relationship while having children.
What we need to teach young people is that fulfilling your every whim and having babies with whomever is not a good idea. The person in this thread obviously does not understand that.
