I doubt that all women find you creepy. For one thing, we haven't all met you and not all of us are into online dating. Maybe examine what you are saying to these women. Do you start off talking about sex right away? Are you only targeting women much younger than you are? Do you read their profiles before messaging them or do you go on looks alone? Do you have a detailed profile about yourself? I know when I was doing online dating, I would find it creepy when someone messaged me and hadn't even bothered to fill out his own profile. I want to know something about a person, not just see a photo.
