Search Results: good age for first time

My aunt was raised with overprotective parents. They wouldn't even let her sleepover not even with a female friend. She would secretly date her HS sweetheart. Her uncle caught them making out once and made a big scene, dragging her all the way home, yelling about how that's not how young ladies behave, told her parents about it, etc. She got banned from seeing her boyfriend. Her parents were too focused on her waiting till marriage, never drinking nor smoking, that type of upbringing.

Result:
She didn't wait till marriage.
Her HS sweetheart wasn't her first and only boyfriend ever.
She was into parties for a bit as an adult, enjoying the freedom she never had.
She married her 4th boyfriend, a very liberal man.

Liberal/permissive style
She and her husband only had a daughter and she was raised in the liberal manner. She was allowed to go on camping trips and excursions (far from home) with friends, went out on a date at the age of 14 for the first time, didn't have a curfew and at the age of 16 got lectured about safe sex. My aunt didn't want to make the same mistake her family did to her.

Result:
She got pregnant at the age of 18 with her 3rd boyfriend.
Her ex boyfriend still pays child support and is in contact with the child often.
She's now 27, married with another guy and they have 2 kids.
My aunt and her husband thinks they exceeded on her liberalism.

Obviously neither extreme is good but which do you think is worse? Overprotective or very liberal parents?
