Konnichiwa, Tatsuyama. (こんにちは、龍山さん。)
You asked for english so I won't scare you with my japanese language skills.
Well, the existence of this forum shows there are dedicated western fans.
I am an adult anime and manga fan. I read and speak some Japanese so I do have a collection of japanese language manga and light novels.
I especially enjoy seinen but there is some shoujo and shounen anime I've enjoyed.
Recently, I've enjoyed watching Usagi Drop, Youkai Otome Zakuro, K-On!, Spice & Wolf. Also Toradora!, Working!, and Bakamonogatari. There are others as well, but I think that list will do for now.
I also study Japanese culture in general (I didn't start enjoying anime and manga until about 10 years ago). My wife is Japanese-American and our life reflects an interesting combination of Japanese and Irish-Norse aspects.
I sometimes wonder how some other western fans can follow a story at all when they don't know basic principles of japanese social expectations. Often they don't understand why a character behaves as they do.
Hopefully, that wasn't too complicated or too simple to read
