It seems you haven't been here a while.
(New to /a/ is like saying "I am a huge faggot please rape my face" on here)
Your best option for finding new anime is just lurking moar. Yes, it's cliche to say that, but despite the troll threads and the faggotry, there are a few of us faggots who actually post legit responses, and can give you an idea of what is good and what isn't worth your time.
Your best bet is to just pick a more popular anime from each genre and watch it, just to get a rough idea of what you prefer and what you don't. If you like the first few episodes of the show, then watch the whole series, and find others that are remotely close to it. That way, you start with one genre, and slowly branch out to other series, which may lead to your liking of other genres in general. And for god's sake, just enjoy the show. Unless you want to find deep meaning in your anime, there is no point of overanalyzing the show. Just sit back and enjoy it. </srsbsns>
