Yaoi, Yuri, Incest and Hentai?

If you would ask me, I'd say that I find yaoi quite enjoyable, though I can't say the same about yuri and incest. Yuri just doesn't get me excited as much, probably because I'm a girl :/ It's true what they say though, girls like yaoi while boys dig yuri. But that doesn't really explain why I don't like incest. It's probably because I don't think it's particularly correct. Like nejihina, I don't understand that! Hinata belongs with Naruto and Neji with Tenten! But I haven't covered hentai yet. I think hentai would have to be my favourite actually. After watching Green Green I think I really started to get into it. I enjoy it over yaoi because as much as I like it, it seems a tiny bit wrong and with hentai, you can't go wrong with that. What do you think? Comment below and tell me your thoughts on all of them.
