OK, so before I even a call a girl, I will usually send a text that says something like:
ME: "OMG, something totally just reminded me of you..hahaaa its kind of an awkward situation but its funny"
HER: "OMG what is it?!"
ME: "Too much to text, hold on..I'll call you in a little bit"
And then I'll call her a few hours later
When I call her, I DON'T tell her a DHV story, I just tell a short funny story. It doesn't have to be anything amazing, just something that will get a quick little giggle or chuckle.
For the longest time I was telling this story that Sinn taught me about this girl who farted at the gym, now usually I'll just tell a stupid little story about how I saw somebody fall flat on their face as they got off the bus or how I saw somebody from my childhood and I accidentally said something rude to them or for awhile I was telling this story about a job that called me to see if I wanted the job, but I accidentally cursed them out a little and hung up on them because I thought they were a telemarketer.
She will usually laugh and then when she asks why that reminded me of her (sometimes they won't even ask, because they got so caught up in my story that they forgot that I originally said it reminded me of them) but if they do ask, then any stupid little reason it reminded you of her will do. It could be something like after I saw the girl fall flat on her face, I ended up striking up a conversation with her and she told me she plays soccer just like you play soccer or anything like that..
I like telling a quick funny story like that just to break the ice of the first time talking on the phone with her, but after that, I'll just start talking about my day or the things I have coming up this week that I'm excited for. You can ask her if she's been up to anything fun lately.
So, to answer your question, you don't need a lot of attraction when you're on the phone, because you should have already gotten a good amount of attraction in the initial interaction, but its a good idea to start off with a little attraction. You should start to get into comfort building as soon as possible though, and then just throw in playful teasing or role plays here and there to keep it light and flirty. (Just a sidenote: whether its phone game, a date, or the initial interation, you ALWAYS wanna be trying to push it forward, so you NEVER wanna stay in attraction for too long, but that doesn't mean that you stop teasing her all together).
To get her to talk about herself, you just ask her questions about herself. A really good way to get the ball rolling is to first talk about YOURself. So, you could talk about how you're really passionate about music or art or whatever your passionate about, and then you can ask her if she has anything in her life that she's passionate about.
As far as day 2s are concerned:
Don't go on Day 2s...Go on DATES. Don't be ashamed to tell the girl that you are going on a DATE with her. Dates have a more sexualized vibe, so they are better. Fuck "day 2s."
To ask her on the date, I keep it really simple. After we've talked for a little while, I'll just simply say:
"Hey whats your schedule like for the next few days?"
Then, she'll tell me what she has going on and then I'll be like:
"Ok, well we're both free xyz day, so lets hangout that day. That would be the best day"
I basically just assume the sale. I assume that if a girl picks up the phone when I call her and she enjoys having a conversation on the phone with me, then she will be happy to go on a date with me.
As far as how long you talk for: that varies. I would say talk for about 30 minutes if you want to be sure, but of course that rule is very flexible. There have been times when I talked to the girl on the phone for 2 minutes before setting up the date and there have been times when I talked for an hour and half. If I'm genuinely enjoying talking to her, then I might just talk longer.
But, a general rule of thumb is that, the SHORTER your initial interaction is, the LONGER you should talk to her on the phone just to make sure she's comfortable. Of course, this rule is also pretty flexible. I had a girl who I met at CVS pharmacy and our initial interaction was literally only 2 minutes long and I ended up setting up a date through text and not talking on the phone at all. She invited me straight to her apartment. Those are the BEST dates
But for now, while your still getting comfortable with the phone, I would say try to have at least a good 20-30 minute conversation just to be sure and also just to get more practice on the phone...
I know this reply was kind of long, but hope it helps....
