The whole "all you have to do is be a female and men will flock to you" thing is rubbish. Sure there is a population of women out there who draw men to them. But there are also plenty who don't. I can only remember one time in my life that a guy has come up to me in public to flirt with me (apart from at a bar or club). If you go about your daily life in a certain manner, which I think many aspies do, where you give off a vibe that you are not interested in being approached...you won't be approached. Life will just carry on and love will be unlikely to find you.
What is my point? Basically that (again apart from my partying days when I went to bars and pubs) I had to put effort into creating opportunities for men to engage with me. These included online dating and finding a meetup group where similar-minded people gather. Almost all of the attention I get from guys is from online dating, then a small amount from the meetup group, then a tiny tiny percentage from other places (like maybe a guy I work or study with). If I didn't bother with online dating, and didn't try to find an activity that suits my personality, I would get verrrry little attention from guys*.
You mentioned something about who would want to date a really quiet person? A friend of mine married a super duper quiet person. They met at church. So again, there was an environment of like-minded people created. It makes attraction much more likely than in generic situations like at the supermarket or at the gym, where basically anyone could be there.
Another thing I do (which just comes naturally) is put in equal effort with the opposite sex. If I'm not approaching them, I can't really blame them for not approaching me! At this meetup group, I've done just as much of approaching guys as they have of me. Basically if I meet someone I like, I try to show interest in them. I ask people out (and yes, get rejected. Everyone does.). I make it less about "how come guys aren't interested in me?" and more about "hmm who might I be interested in?". As I'm interested in aspie-types, it's likely that they could be sitting there feeling that nobody in interested in them! Why shouldn't I be the one to make the first move?
I'm not saying you're not trying these things (apart from online date which I'm pretty sure sure you said you haven't and won't try), but if you aren't, my suggestion is that you do. Of course you don't have to and if you want to give up on love, that's fine too, I hope it makes you happier

*that I know of. I might not realise when a guy is paying attention to me in day-to-day life, and you might have this problem too.
Fantastic post.
I would add that males not coming over and initiating is perhaps a sign of the times, mutual respect is lovely but it will tend to make us standoffish at times.
