I agree with ptangptang; It's important to feel good about yourself first. For me that's still a work in progress a lot of the time, lol. But I think everyone, both male and female, find confidence attractive. Also, once you are happy in yourself and your life you will have the confidence to admit when someone isn't right for you. I think that you need to be honest with the people that you meet online. When looking for a partner it's personality and compatibility that really count, and so those are the things that people should judge you on.
