Now I kinda do, and I flirt and tease more, I tend to be more direct (not too soon though) and I am more open and funny, but I don't see change in girls answers. I do feel like I am improving a lot, and my friends and female friends notice, but still no luck with the girls I like.
by the way, I am muscular fit and well groomed, so I don't think it's due to looks.
