I don't realy have an anime I'm ashamed to enjoy, but if I have to pick...
  I guess Hamtaro, or  Hiyokoi.
Hamtaro, because it's ment for Children, and Hiyokoi cuz it's ment for Girls (Shōjo).  But I'm not ashamed as much as, like, slightly embarrassed 😅 There both Good anime, with good story's and are fun to watch
