aggression

 First of all it is not okay for someone to force another person to have sex. It sounds like you are not in a healthy relationship with your boyfriend. It is his obligation to acknowledge and respect your choice to not have sex.  If he is forcing you to have sex then it clearly means that he does not respect your choices as an individual. I would suggest to you that you should walk away from this relationship. You deserve to put yourself in a relationship that enriches your life, adds to your feelings of self-worth, enjoyment and growth.
