I'll give several less mainstream but good quality anime. They will unlikely fulfil the male fantasies 14 year olds and possess little ecchi.

Arslan Senki has good pacing, animation and interesting characters. The main character might start off frustrating to watch but his development is handled wonderfully AND realistically. You can really see him grow.

Mushishi has been hailed as a masterpiece even though it never achieved mainstream success. It has a relaxing and episodic nature. It won't give you crazy hype or make you thirst for the next episode but it's the kind of show that you watch and just go "that was really good..."

Ping Pong totally put me off with it's art style at first. I would have never given it a chance if not for the amazing reviews it got. Give it a shot, you'll ignore the unique or what some people consider to be ugly art in no time. God damn is it amazing.
