1.) How can a chick ask a guy out?
If it’s someone you know, go up and say “Would you like to do activity X on Y date?”. Or phone, or IM. Otherwise, strike up a conversation, and when it feels right, say that same question. Don’t drop hints and rely on the guy to pick them up and ask you out. We’re notoriously dense and this method will only leave you frustrated.
2.) Guys/not-straight girls, if a girl were to ask you out, and she wasn’t a knockout (though not ugly), would you say no?
If she were someone I already knew, then probably–the women I know who would be comfortable asking me out are women I’d at least give a chance. Otherwise, yeah, I probably would, just to see what she’s like. Remember, what actually makes you attractive is between your ears. Physical attraction will help to get a conversation started, but after that it’s not entirely relevant.
And of course, guys are hornier than girls. Use this fact to your advantage. 
3.) Opal, will you go out with me? 
Response hazy–try again later.
4.) Guys, would a girl asking you out freak you out?
I’d wonder what the hell she was thinking, but no, not really.
5.) What are good things to do on a date?
Anything that you think sounds like fun for two people to do together. Some activities, like going to the movies, don’t afford you much opportunity to get to know each other (at least not in a way that you might want to get to know a relative stranger). Dinner is a good choice; minigolf is popular. Use your imagination and your knowledge of what’s available. As you discover more about what interests you share with somebody, you can adapt what you do.
6.) And how fast do relationships progess?
Ideally, at a speed comfortable to both participants. If it doesn’t feel right, it isn’t.
