Well, that’s kind of a personal question and depends on what kind of person you are. It could be a number of things. Maybe you’re giving off the wrong vibe, or maybe you’re coming across like you’re nervous or not interested. A few years back, I found myself having the same problem. I went on a string of first dates that never led to a second, and I just couldn’t understand why.
I read a few posts on this blog, and I realized my attitude to dating was all wrong. I was coming across as the ‘best friend’ type and not an Alpha male, and I figure this is what was putting women off. I got a ton of advice from that blog, and so far, I’m doing a lot better on the dating front, so I’d definitely recommend giving it a try. Without knowing more about your situation, I can’t really help more than that.
