[MM] Cheating on my gf with my roommate

Originally posted about my experience in r/gaystoriesgonewild, someone suggested I should post here.

I was a freshman in college. I always thought I was straight. I was into girls, I fantasized about girls, I dated girls. Specifically, at the time, I was dating someone I knew from high school, call her Kate obviously a fake name). She was in the same friend group since freshman year, and we started dating junior year. We were both studios and were accepted to the same state university–not that surprising since state uni accepts ~40% instate students.

Anyways, first day of college, we drove with each of our families to uni, we unpacked, each had dinner with our family, and met up and explored the campus. Because we had come so early, I had not met my roommate yet. When I came back, it was night, and he had already unpacked his stuffs.

I was surprised when I first met him, let’s call him John. We couldn’t have been any more different. I was moderately tall (5’8) with blondish hair, and slender frame with a boyish look. He was maybe 6’3, with ragged brown hair and beard, with a muscular frame. I felt small in front of him. When we shook hands, I noticed how bigger, and rougher his hands were to my smooth hands.
