>>8687527Other two anons covered the most important points, but you should also get better at making conversation. You can probably talk to your friends without sounding like an idiot, but when you're talking to people you don't know well and are attracted to, it's damn hard not to spaghetti all over the place. Learn to talk neutrally- instead of 'I hate this show' say 'This show isn't really my style', never call other people crazy without an excellent reason (Naruto headbands in school is not a reason; making a shrine to a fictional character, complete with blood offerings, is a reason) and don't laugh at/insult other people to make yourself look better. Seriously, don't. It makes you look like an immature dick and is the reason nobody on /r9k/ has had a healthy relationship (assuming, optimistically, that they ever had one). I know this all sounds condescending as hell but believe me you will sound a lot better, nicer, and less desperate if you do these things. Make an effort, it'll be super worth it.
Go to a con for fun. Meet people because they're into the same stuff you are and if things work out, you'll get a girlfriend. If they don't, you get a friend. Don't give up after the first time. You might be tempted to go on a self-pity trip if nobody wants to talk to you, but these things take time.
Also- don't call other girls sluts or whores or bitches. Especially don't do this to other girls. They won't think they're special for being different to those disgusting females a gentlesir like you so despises, they'll think you're some creep who's probably on a government watch list for unhinged stalking. Just don't mention your anime club members if you can't stop the rants from pouring out, but be yourself otherwise.
Also this ended up being a lot longer than anticipated. It's p repetitive but important. Basically, don't be a dick or creepy and you'll be fine. Go forth and have fun.
