Learning a language to get laid

Can it really work? I'm not talking about learning japanese to get a waifu but what about spanish to get a latina or something?

It can't hurt. But there are blaring prerequisites that, if not met, could stopper your progress.

1) You need to be attractive already
2) Your language skill needs to be good to fluent
3) Your accents, tones, and delivery need to sound like a native speaker, and a suave native speaker
4) You need to be attractive already

Some girls will find your ability to sound like a native speaker (while not being one) extremely attractive, but only if you are. If you have no confidence, weigh 80 pounds, and look like you got hit by a bus, you're chances of picking up women in any language fall off a cliff (unless you're fucking loaded).
