I’m 18 now and in a happy relationship of 3 years with a girl I love, but I keep thinking of when I was 15 and single and how I was able to pull girls like it was nothing. Nowadays I don’t even get looks, and it’s not that I want to be with other people, but I feel really sad that something changed with me, either superficial or behavioral, that caused me to seem unattractive in comparison to my 15-year old self.
