300L UNILAG Student Writes In, Says My BF Is Asking For Sex In Just One Month

I have tried to make him understand that he should give me sometime but according to him he needs to make love. I broke up with him because he doesn't seem to understand me, I feel if he gets  sex he would start misbehaving and I don't want to ruin the connection between us. Is there any rules that goes with sex in a relationship? I don't know if I made the right decision in ending it with him... A friend told me you have to take risks in a relationship. Is this true? I need advice pls.
