Advice from the old lady:
Here's what the guys are really asking you. Did you kino during the date? Did you cozy up to her in the booth? Did you kiss her or steal a kiss from her? Graze her neck with your lips? Blow gently in her ear? Did you place your hand on her thigh? Did you physically touch her in any way to verify all the saucy things she was saying? Or were you polite and sat nicely across from her having a conversation? THAT is what the guys mean.
Latina women are from a touchy culture. The men are very machisimo. Men who are masculine are sexually forward and this is especially true of Latin men. That means they invade the personal space of a woman they want. Latina women respond to this. MOST women (if they are attracted) respond to this. Kino means you are not a "nice guy". You are a sexual man and you have desire. One of the sexiest things a woman wants is to feel desired.
She isn't going to go home with you if you weren't into her physical space. Conversely if she refuses you getting into her personal space (aka she turns down sexual forwardness) then rest assured she isn't into you and move on. This is part of qualification. It goes both ways. You dropped the ball here (sorry).
Her calling you up to discuss what you are looking for like a job interview simply means she is entertaining the idea of stringing you along as a sugar daddy/citizenship sponsor. You didn't give the right answers there and you didn't create desire where she was open for sexual contact so she's out. Period. End of story.
Learn how to get touchy with women (without being creepy.) Trust me you do that and you'll go far. The post
@mrgoodstuff is talking about is about men who yes in many cases with screw anything on two legs, but the bigger point is they will flirt shamelessly with anything on two legs. And I'm here to tell you, men who can flirt with anyone can score with most anyone...which means these men can afford to be more picky as they move up the confidence scale. I've been dating just such a man for a while now. He was extremely touchy on first meet. Very sexually forward. Granted once actual dating starts that is its own can of worms, but the men who are physically forward (learned from practicing on whoever) are the ones that get the hotties revved up.
Now as far as meeting high quality people? High quality women? You need to seek out places they go and then go there. There will be venues in your area that the beautiful people frequent. Go there. Mix, and mingle, and smile and touch. That is how you build chemistry. Women are suckers for chemistry.
