I think most girls preferred a guy with more bulk than my lean build. Fast forward to midway through my 2nd year, I had just lost 70 pounds but was still a virgin.
I started noticing less girls smiling at me and eventually started working out and going on a vegetable diet. My first year of university, I gained weight. I dressed poorly, and was starting to become overweight.
I came from a sheltered middle upper class upbringing, but was raised to be cheap. Leaving high school and going to university, I believed I was completely straight.
