I'm going to jump in here. The sad reality is that most guys are completely clueless when it comes to women. Let me repeat that, most guys are completely clueless when it comes to women. There is no "right way" to ask a women out. Rather what you should ask is if you are the right guy or not. That's the only thing that matters. If you are the right guy, then it doesn't matter how you ask her out, if you are the wrong guy, then no matter how you ask her out it will be wrong. Stop looking for a bag of tricks and start focusing on becoming a man. That in a nut shell is what women are looking for. Women want to be with winners not losers.
Women would rather, many times over, compete and pull their hair out trying to figure out how to make a winner their own, than settle for a loser. When you start winning at life, you will naturally give off an air of confidence. Women can sense this like Spider-Man can sense bad guys. You want to know the secret to getting women, turn yourself into a guy they want to seduce. When that happens, you can talk to them normally and their panties will be getting wet. Women know whether you are a guy they want to seduce before they even talk to you. Let me repeat that, before they even talk to you Women know. This is why it's so important to be aware of your surroundings. When a woman just pops up out of nowhere and is giving you signals that she's interested that is the time to pounce. You make think that that was a random occurrence but I assure you it was not. She probably scoped you out, decided that you have the potential to be the man of dreams, figured out your normal routine and placed herself in your daily path.
Now let me ask you a question, if a woman does all that, do you really think it matters how you ask her out. Like if I say, 'Hey, let me get your number" or "Miss you're beautiful let me get your facebook and we can continue this conversation online" do you really think it matters. Trust, off the sheer thrill that all her planning has born fruits, she'll barely be able to contain her excitement. Her sympathetic nervous system will have already started to prepare for sex and in her head, she's already planning out how the relationship will go. Stop focusing on girls, and start focusing on becoming successful. Focus on getting your money up, focus on improving your social skills and focus on becoming a leader. You do those things and you'll have to beat the women off with a stick. And then you can see the ugly side of life. Regarding that I'll just say this, natural human attraction is one of the strongest desires that human beings have.
