I like the "challenge email"...way better than a neg.
It will read something like this...
"You are obviously a very attractive woman, but if you were in a bar or nightclub and everyone else there looked exactly like you, how would you separate yourself from the crowd"?
Do you see why that works so much better? It's a compliment. But It also says that you want to challenge her mind. My response rate from this type of email is pretty high. I'd say around 75% I'm not a good looking guy but my picture is shown on my profile.
Anyways, once she has responded, don't overdo it. Just proceed on making small talk. What were your favorite tv shows growing up? Things like that.
3 emails and NO MORE than 3 emails ask for her number directly.
"Hey, I am having a great chat with you, but all this typing is giving me carpal tunnel sydrome, why don't you give me your number and we can chat sometime."
Just come out and ask. Now it is crucial that you ask for her phone number after 3 emails. You don't want to become her pen pal. She will get bored and forget about you.
A few years back, I had this great conversation flowing with a beautiful girl, about 8 years younger. We had a lot in common, grew up in the same neighbourhood, exchanged lol's etc. I must have sent her 10 emails and never asked for her number and then she disappeared. I wondered what I had done wrong. Did I say something offensive to her? Did she just meet someone else in real life?
You see I was kind of fixated on movies and tv versions of online dating like the movie "You got Mail" with Tom hanks and I thought email exchanges should last for weeks before taken to the next level. But women who are online dating DO NOT WANT TO BE ONLINE DATING, THEY WANT TO MEET GUYS IN PERSON.
