I've written this for guys, but really it can be applied to both genders.
Right now, in Vancouver, most of the men are gun-shy to the point where most of the natural flow in hooking up with someone is gone. This doesn't really help either side, and responsibility can be laid at the feet of both sides of the equation. What it does lead to is an environment of "do-or-die" where everything's on the line, which can lead to a rather over-balanced sense of failure.
In my time here I've been the recipient of 'the stare', where a guy will look intently at me hoping to generate a connection. But this doesn't really work that well, all it does is build up the tension and expectation to a level where the casualness is gone and suddenly there's more on the line and it is difficult for both sides to deal with.
I've also had a guy catch my eye a couple of times and then back off. After a while it's as if he screws up his courage and starts trying again, but then if I miss one or two of his eye contact attempts no matter what's going on around me, he gives up and stops looking almost immediatlh. This leaves little room for the 'being human' portion of the interaction - the girl getting nervous for a minute, the guy getting nervous for a minute, either one having to pay attention to the friends or family that they're with for a moment. What it does do is make sure the girl is basically ignoring what's going on around her while he makes his move, or leaves him feeling demoralized if it doesn't appear to work out in a very short period of time. Again, a harsh recipe for failure for both sides.
In reality, establishing contact has more of a flow to it. It can have moments where either side has to take a moment to deal with nerves, or has to pay attention to friends or family, and then comes back to establishing or maintaining contact. The question behind the establishing contact does not have to be answered immediately by both sides; though it should probably be answered by the end of the evening/outing.
But there's one more item that's key & that can make this all a lot easier, and that's the intro conversation.
When you see someone you like, you have part of the picture. But you don't really know if they're compatible until you've talked to them and gotten to know a bit about them. So, really, a short chat is important.
And when you build it up too much before you have a chat, then that makes having the conversation that much more nerve-wracking and scary. Putting more on the line the longer you "think about it".
See, the thing is, this intro conversation doesn't have to be the end-all and be-all of the whole interaction. I mean, if it fails you still had a chat with a pretty girl/hot guy. Bonus!! That's one more conversation than you had earlier. And if the "thanks, but no thanks" is done politely, then there is much less let-down. Maybe the conversation doesn't go in the direction you wanted, but you still met a pretty cool person & you stay in contact as friends or acquaintances. Bonus!! That's one more friend/acquaintance than you had earlier. And if it did work, you're off to the races. Wooohoooo!!!
If she doesn't talk to you or seems unwilling - that's her issues, not yours. Say a polite farewell and move on. If she chats with you, you're on your way. (There are plenty of girls in Vancouver who moved here from other parts of Canada, for them a conversation won't be a scary thing.) If you get a "thanks, but no thanks", well, that's just more practice under your belt for next time.
The thing is, striking up the conversation is a much more clear way to know where you stand with a girl; much more clear than giving easy to misinterpret signals or setting yourself up for a situation that favors harsh failure. And trust me, if she likes you she will help you with the conversation no matter how nervous you are.
Also key here is being open to conversations. Just because you're open to a conversation doesn't mean you're forced to accept whatever the other person is trying to say or do. And it doesn't mean you're suddenly limiting your options. What it does mean is that you've made it much more psychologically easy to get to know someone, because it's only in the getting to know someone that you find out how much you really do like them.
And just because someone looks at you, or smiles at you, or even strikes up a conversation doesn't mean that they're going to jump you. It just means they may want to talk to you to get to know you; and to see where it goes.
One big complaint I've heard about on the flip side of the issue:
There's been a lot of conversation about how girls expect guys to pay out, and how some girls won't go out with a guy on the first date unless he pays. For me, I find that a bit odd and, given how much things cost now, rather a bit of an unfair burden for the guys - especially on the first recon. date where we see if we're even basically compatible.
Personally, if a guy just chatted to you for 5-10 minutes & offers to take you out to get to know you more, I'm inclined to pay my half. For the simple reason that we don't even know yet if we're even vaguely compatible. I'm just as interested in getting to know him as he is me. There are many other ways for a guy to show a girl that he's interested than paying up front - holding doors open for her, opening the car door for her, etc.
However, if it's the 2nd or 3rd date, or if he knew me before he asked me out, then yes he should pay. At this point it's more of him showing his invested interest in the girl, and therefore he has more of a reason to show a girl how he will treat her and what she means to him. But, by this time, he should know if he's serious about getting to know her. Personally, for me and depending on the circumstances, I may end up offering to pay for some of the dates going forward.
Equal rights swings both ways ...although some gender-based role playing can definitely up the sexual tension in a good way.
