Is this a Zombie? is ecchi and comedy, and the main character is a high school student.

Rosario Vampire is another good one that fits your criteria.

Try To Love-Ru. It has comedy and it is ecchi.

Baka and Test.

One of the most hilarious animes I've seen so far.

I honestly hate hentai and Ecchi. So I won't Список any if them. No offense to those people who like them.
