After living in Hungary I picked up on the fact that mother/son relationships are not what they are in the rest of the world and what we in the States would consider too close. I heard that it wasn't uncommon for married men to take their laundry home to their mother's house on the weekend, etc. Western Romania is still strongly ethnically Hungarian, so that could account for the similar prevalence there.
You heard right. Nudity is also more prevalent than in the western cultures, it's completely normal for a child to see their parents naked, even in their teens and beyond.
