I don't agree with the sexist negative generalizations, I don't agree with the sexist positive generalizations.
Generally I've found that asking girls out is the fastest way to ruin a relationship. No matter who it is. Even the most intelligent woman will often turn into a condescending asshole the instant that I ask her out (or she thinks I'm going to ask her out.) It's very rare for me to meet someone who actually appreciates being asked out. Which is ironic, from my POV, because it seems that women choose to provide the majority of the 'risk'. Have a great friendship with a girl? Forget it. That seems to be even worse because then you know her and can be more of a threat.
Obviously I'm not a girl, so I don't know exactly why so many women choose to act this way. Neither do most women; they don't even bother to consider the consequences of what they're doing, they just label a guy negatively and be done with it.
So I used to recommend to people that they ask girls out, but now I generally don't. Women seem to be more likely to be assholes because they expect to be spoiled by attention and to be able to take guys for granted and treat them like dirt. There's still enough chivalry alive in society today that people have issues with people who respond in kind to women.
So I don't think that blind faith works any more, or that you should automatically assume that you're not getting any just because you haven't asked any girls out. Remember, it's the 21st century, women are fully capable of displaying interest and asking guys out as well. I've yet to hear anyone give a good reason why guys _must_ be expected to ask girls out that doesn't rely on extremely shaky reasoning.
So really, it may just be that you haven't met anyone who's a decent person and/or you get along with. If you don't feel comfortable asking a girl out, she may pick up on that and assume it's insecurity or that you're not really into her, get insulted, and blow you off. So it's in your best interest (and probably everybody else's) that you only ask a girl out because you believe it's worth it and you actually want to, not because somebody told you that it's the only way you're getting laid. (Remember, hookers are legal in at least two counties in Nevada)
That's probably more enticing flamebait than the little personal war we had going on.
