I do nothing besides watch anime, play video games and go to college. Prior to that I was just at home watching anime and playing video games. My list would probably hit the post character limit. I will post my top recommendations.
-ACTION-
Elfen Lied - If you haven't seen this, even if you don't like anime, it is worth watching. (Blood gore nudity)
FLCL - Classic laid back fun to watch. Available on youtube. (Action)
GATE - New favorite. Answers your question about what happens when Mid-evil knights go up against current military. (Manga has blood, gore, nudity, and more adult themed stuff, anime is pretty suggestive so far.) Avail on crunchyroll.
Chiyaharafuru - Not your typical run of the mill anime. It is about a card game, an actual card game. Despite it being about an actual card game, it is very interesting and a good watch. Avail on crunchyroll.
Time of Eve - A awesome short anime about humanoids living with humans and realistic issues that arise with it.
Another- Very interesting anime about a cursed high school class.
Vampire Knight - Good watch, ending kinda sucked.
Fruit of Grisasia series - Awesome show, very deep, everyone has a pretty sick and twisted background.
Sword Art Online Series- Overhyped imo, it is good, well the first season.
Attack on Titan- Pretty awesome action show.
Is it wrong to pick up girls in a dungeon? - Similar to Sword Art Online, Main character can be OP.
-ROMANCE-
Clannad & Clannad: After Story - Amazing love story mixed with slice of life. MUST WATCH. Avail on Hulu
Plastic Memories- Another amazing show that will hit you in the feels on the first episode!
My Love Story- Very cute couple going through basic things together. Very happy and awesome anime.
Love, Chunibuyo, and other delusions- Cute little Harem
Ano Natsu de Matteru- Biggest love triangle I have ever seen in an anime, not overplayed pretty good watch.
Kimi no Todoke (From me to you)- Cute love story. Girl looks like the chick from "The Ring" horror show.
Blue Spring Ride - Two HS students falling in love.
Say "I love you" - Two HS students falling in love... Very similar to Blue Spring Ride.
Angel Beats- Somewhat interesting love story.
Toradora!- Another HS love story, pretty decent and awesome first kiss.
Nagiza Haruka- Interesting show about a girl who accidentally exposes her love for anime/manga ect. Love story.
-SLICE OF LIFE-
White Album- This anime pissed me off, well mostly the main character. About a man and his girlfriend who is an idol going through different things.
White Album 2- Similar to one but 100% better. (I don't really recommend WA1, but I do #2) Based 10 years later from WA1, totally diff characters.
Ef - A tale of melodies - Good show follows multiple stories with deep backgrounds. Somewhat of a love story behind it as well.
Ef- A tale of memories - Second season of the prior mentioned. Both are pretty good.
This is a "small" list for me. I will now go reassure myself that I am a man, and that the internet is a figment of my imagination.
My list of anime watched is VERY extensive, if you have questions about an anime, or want recommendations, OR want to know if a show is appropriate for your child, feel free to ask me. I typically like love stories or action.
