You look pretty normal. Get a haircut and gain some muscle and you're easily better looking than the vast majority of men.

You shouldn't settle for unattractive girls (someone who's a 4 or worse). I did once and it was not a happy relationship. Some ugly girls are completely oblivious to their own lack of qualities and will gladly hit on men more attractive than them; also, since these girls get hit on less than other girls, they're more likely to take the active role.
Many men with AS are kept in an artificially low league because of poor social skills. The best thing you can do, is to find a workaround for this. Every social flaw (i.e. the smaller your friend circle, the less you like to party etc.) is something you somehow need to compensate for. Sadly, finding girls who aren't into partying, clubbing, binge drinking and all that can be a tough task...
Not if you go to the gym. There are tons of girls that stare at me, some of them smile, actually quite a few. The only thing I need to get past is noticing what the heck the ladies are doing when I am around them. I feel quite clueless sometimes.
