Green Green, B-gata H-kei Recommendations
They center around pervy teens. Both series have highly perverted comedy and wacky situations.
Another VERY funny ecchi anime! If you liked B gata H kei you will laugh your ass of while watching Green Green, I know I did!
Green Green and BGHK are both crazy comedies including lots of romance and plenty of ecchi. Both animes are revolving a lot around the fanservice, even though I'd say that BGHK have more of a plot, and I think most people will appreciate that anime it more than Green Green, which mostly consists of plain ecchi and bad jokes. Although I watched - and loved Green Green. I watched B Gata H Kei afterwards and found it great as well. Since I loved Green Green so much, I had it in mind a lot of the time while I was watching BGHK.
If you liked Green Green, you will surely love B Gata H Kei. Both have pervy jokes centered around fanservice but the latter one has actually a complete story unlike green green which doesn't completely explain the story.
