So I used to be out of shape with acne and didn't care about my appearance until I went to college. Then did cardio lost weight then got into shape, cleared up face, etc. Started lifting weights, doing powerlifting etc. I also learned that talking to women isn't hard, so I could see signs of girls attracted to me and also how to spike emotions etc. However since as a 20 year old I have restive inexperience with women, even if a hot girl talks to me and I know she's at least somewhat attracted to me, my mind doubts it due to the bad stereotypes before. Similar to when a girl gives me eye contact in public that just isn't friendly etc. And when a girl initiates touch etc. and hugs. I know I'm more attractive than when I wasn't but that nagging voice is hard to shake. How can I do it?
