I’m a 17M who lives in upstate New York. I’m slightly introverted, I’m like in the category between introverted and extroverted, but fall more into the introverted category. In a month my school will have the Junior Prom but I’ll be out of the country. What I’m getting at is that I have just over a year to find someone to take to the prom. I’ve never had a girlfriend, even though I’ve always wanted to be in a relationship like that. I’m not attracted to anybody at my school and I’m not sure what to do. Any advice is greatly appreciated!
