I must chime in that anime is 100% not a girl thing AT ALL.
In Japan there are categories of anime specifically targetted at all demographics and the most popular anime in the west are usually the big shonen series. Shonen meaning boy.
Shonen (=boys anime) - Death Note, Naruto, Bleach, One Peice, Fullmetal Alchemist, HunterxHunter, Sword Art Online, Attack on Titan etc. (basically every highly popular anime in the West -NOT FOR GIRLS)
Shojo ( = girls anime) - Sailor Moon, Fruits Basket, My Little Monster, The World God Only Knows, Kokoro Connect etc.
Seinen (=adult men's anime) - Berserk, Tokyo Ghoul, Durarara, Ghost in the Shell, Monster, Space Brothers, Re-life, Golden boy
Josei (adult women's anime) - Nana, Chihayafuru, Gokusen, Usagi Drop, Shouwa Genroku Rakugo Shinjuu
Tell me most of the anime you watch isn't specifically targetted at men. I'm sure you can't.
