So what do I do about this one Yuri Anime?

It's called Sono Hanabira ni Kuchizuke wo: Anata to Koibito Tsunagi Well I've heard it's a Hentai and that is soooooooo not the type of ऐनीमे genre I would ever watch at all. It looks like such a cute ऐनीमे though and I absolutely प्यार that Yuri couple. I've watched a clip of it before too, but it was a clip that didn't have any Hentai in it and it was so cute. Well I've watched quite a few Ecchi ऐनीमे so far, but I don't really watch it for the Ecchi. It's just that I happen to find some of the characters in it very cute या because I like the story line. I'm not really an Ecchi type of a person either nor am I really perverted या like perverted type things. I guess the thing I really need to know is are all of these hentai clips in that ऐनीमे really that avoidable? Should I take a risk at watching it या not? Would Sono Hanabira ni Kuchizuke wo: Reo x Mai Diaries the ONA (Whatever ONA even means.) be better for me to watch since it doesn't say it has any Hentai? Some people say all of these series aren't even really a real Anime? Then if not what is it? Plus does this ऐनीमे (Or whatever it is.) even have English subtitles so that I can read what they have to say या not?
