i think at 15 your in no way sure to know what love really is and you will see that much later trust me.a love of a 15 yr old and the love of a 18+ is very different, sex bring on lots of things not just kids , it can actually change the way he and other people view you , i dont think at 15 its a good idea to be sexually active without first having a job, a house and a car, because how do you know if and thats a if which could 50% happen that he will want you or the kid after you have it? he is young as well he is in no way to be a father he has to be at 14-16 yrs old still figuring out life , if you love each other you will wait and not screw each others lives and futures up,kids cost alot avg baby cost atleast another 600$ min per mth so get a job, car and house and dont burden yours or his parents
