The question is if you leave an impression that it's possible to get anywhere with you. I'm not especially for obnoxiously loud girls although I've met some nice ones.
It's more like, okay, so you're shy. Is it because you're not experienced, don't know what to say or do? No problem. Is it because you shun guys and any relationship and talking to you is hopeless?
You can be interpreted as shy in a good way, or in a bad way.
I'd definitely prefer someone feminine over some 'lol here's my asscrack', habourworker's-language, hay-guyz-i-got-hairs-on-my-chest-and-play-jackass-in-the-weekends girl though..
