>SpainI'll assume you meant "treated as normal" and respond to that. In animu/mango, you will generally only find out that characters are in a relationship if it's important to the story or used as a gag or fanservice, gay or not. You don't even always know who is married. The big exception is that most people's parents have fucked at some point, so it's a dead giveaway.
>not just two grills making outLotta love-porn w/ no sexual content at all. Internet/English calls that shoujo-ai (or shounen-ai) because we're bad at Japanese.
>for the sake of fanserviceI can name very few anime w/ no fanservice, and none w/ obvious gay relationships. If you want to watch anime, overcome your erotophobia.
>spoon feed meWatch Marimite. Read (don't watch) Strawberry Panic!. Lurk /u/, they are very friendly.
