Asking men out

I have not had a boyfriend since previous relationship ended. Finally, I feel that I am sorted out, ds is happy, asks why I have not got a boyfriend, I am doing well, and actually I really would like a boyfriend again, with a view to a serious relationship. I have also thought a lot about what I can accept and can't accept, and what I am looking for. However, I am totally out of practice and can't make a move. I used to be good at attracting attention but can't remember how to do it. I never asked men out, because it used to scare them off, but I used to be good at getting men to go out with me in a friendly way, out of which something would develop. Life has changed so much, perhaps because everyone is so busy at work at this age. Nothing seems to be happening. I want to see more of someone who flirts with me, because I need to know more about him and his character before I decide whether I really fancy him. What should I do? I feel very inhibited. I am also anxious in case this person has got a girlfriend, though I know is not married and does not live with anyone. I feel very insecure because I am nearly 30, ie that men will feel afraid that I am too serious in my intentions. Logically I know that I still look attractive, but I am feeling paralysed by insecurity because I have just not been involved with a man for so long. I also feel scared that I have forgotten how to be a girlfriend, having got used to doing everything myself. Please tell me what face-saving ways there are to ask men out. What worked for you?
