overly wanting sex ):

okay so my loving and caring boyfriend is in the Army. We have had sex before but not for a while. He is coming home for Christmas and he is constantly talking about sex. I get that we haven’t had sex in a few months but it is really starting to upset me that it seems like that is all he is worried about , and I have told him and he just gets super offensive , but I love him and ughhh. Well today my mom finally took me to get birth control (I’m almost 18) and they said I can’t start it until my next period on December 16th he keeps telling me how disappointed he is which is even worse than him saying he is upset. I told him either way we are using condoms because I’m not ready for a kid right now. I feel like he is thinking with the wrong head and quite frankly I don’t know why I’m even writing this I guess I just need to feel like someone is there to talk to. I started online school this year for my senior year because I have a lot of medical issues going on , and if any of y’all wanna be friends please hmu because I pretty much have no one anymore :/
