How to deal with not being allowed to date

Savannah
I am 14 and I am not allowed to date yet. Not only can I not date, but I am not even allowed to be friends with boys. There is a guy I really like and he has expressed his interest in me as well but we can't see each other outside of school and we only have one class together. It upsets me that my parents won't allow this as my step sister who is the same age as me is allowed to go on dates with boys and stay at their houses. It makes no sense. I'm the most well behaved of all my siblings but I'm treated the worst. I have made a post similar in the past so sorry if I am annoying. I just don't know what to do about this.
