You don't have to say a word and he'll be hooked.
As a self-professed former shy girl, I can tell you that meeting men can be a downright brutal process.
But it's also true that girls like guys that have a decent amount of normalcy. Even if some experiences are painful, your shy brain will round itself out and become more adaptable to dating situations.
So if you're super shy and trying to date girls, you're in luck because girls love you!
This is that if you're shy you NEED to address your WEAKNESSES. You need to work on your voice to try to become at least a little bit louder.
