College roomate turned me gay

My sophomore year of college my whole life changed. I got a new roommate who is gay and became very close friends. We have a lot in common. A lot of of the same interests when my girlfriend broke up with me he was there for me. I got the feeling he was into me. He would always tell me. I had such a huge ass for a straight guy about six months into our friendship, we are both drunk at a college party where he kissed me the next thing I know we're in our dorm room and he's pushing a huge dick in my big ass and that was just the beginning of it.
