Like what do I need to where (Iwas thinking about his favorite outfit), How much money, and that?Any body have any tips for a first date (14 years old..)?
to be honest, young boys come and go. so if they really like you, all you have to do is be yourself, and he will adore you for it. theres a reason he asked you to go with him and not the girls you will be pretending to be during the date. so be yourself because thats who he wants to go out with.
