The great Ecchi debate

Ya, it is definitely not supposed to be taken as "simply an alien girl eating a banana."

 Spoiler

Posting cause it doesn't actually show any sexual parts, it just implies sexual stuff.

....Is it bad that I've watched this anime before? Sadly, it got boring to me.

Ecchi usually refers to as softcore-hentai. Sexual situations, etc. Doesn't always imply or mean "sex". I see porn and ecchi as two different things. Depends on how you look at something that is being represented to you, as well as how it was SUPPOSED to be represented.
