Omegle is a site that connects you with a complete stranger, and it is completely anonymous. You don't have to sign up for an account or anything. I have found that it is a great way to practice building conversations and attraction. It is also good to test texting lines.
Last night I was bored and so I visited the sight. I hooked up with someone, and I almost immediately knew it was an attractive women. You can usually tell, because they are very withdrawn and don't want to volunteer much information about themselves.
I chatted about any old thing and practiced weaving in multiple conversation threads. I made funny little jokes and cold read into much of what she did elicit about herself (Remember, everything a woman says, is a potential conversation hook). After about three minutes, she told me that she was a lingerie model in London and she had just got off of work. Now obviously, I have no idea if that was true, but since she didn't lead with that information, and it only happened after I had established great rapport with her, I'm pretty sure it was.
Once I learned that, I started stripper game on her. Soon she really opened up, and was telling me all about her life, her ambitions, and what she was studying in school. Soon she was qualifying herself to me at every turn. We talked for about an hour.
The point is, I got a chance to practice all of those techniques, and I got to do it at no emotional risk. I highly recommend that you use the site, especially if you suffer from bad Approach Anxiety. It is a good way to build skills and confidence in your abilities.
