Female - 22 Years Old
Coming from a female, there is no true right or wrong. We're all different and we all react to different guys...differently. But I would have to say that two things that will turn a girl off (or run her off) is to make her feel like she's getting hit on intentionally or being bombarded by questions. Don't interview us, just have a simple conversation and it will grow from there.
I don't think anyone has a magical answer or any perfect advice for this sort of thing. I barely have a clue how to talk to guys. The only defense mechanism I have when it comes to speaking to the opposite sex is to attempt to be funny. Sometimes it works, sometimes it doesn't.
Practice makes perfect.
