To date my best friend/sex friend?

B
There is this guy I have been best friends with since my freshman year in high school. He was my date to a dance that I enjoy the most. We are in college he is almost done and I am pursuing another degree and working at a school. I go to his house at at night to play video games. Then one night we played truth or dare and ended up naked and he gave my first oral and I enjoyed it. Then another night I came over and  he fingered me and gave me oral as I gave him some oral back. We never penetrated because we are both scare of me getting pregnant. We are both busy with college and work. I would love to start dating him someday maybe after school is over. Any advice?
