Women will always think of you as threatening. Our first 2 second glance at anyone is to assess danger. If you have a demeaner that seems to put women off check if you make agressive moves. Determine if you stand too close or say agressive things to get their attention. If you are a non-threatening person they would feel that eminating from you in the first few minutes.
If your post was really to ask "if you would have a chance at any girl no matter what age you are" that is a different story. If you are an old geeser (over 40 if a gal is in her 20's) you have no chance. If you are clean and cute and over 40 and look like you might have money, you will find girls after your money who will adore you.
So the answer is, NO you dont have a chance at any girl. What ever "chance" means.
