It sounds to me like you guys are all pretty young and getting caught up in all this exciting sexual energy. Seems that all these relationships are primarily sexual, and fairly casual, considering how easygoing your bf is about everything. I know it seems like it's love, but... you don't know each other very long. I keep getting the feeling you would be better off focusing on your studies than trying to form a family right now with someone you've only been with a few times. Come back to earth!
