Okay so i got a message on facebook lastnight from a 19 year old that lives right near me he thought i was 17 from my profile pic i told him i was 14 but he said i was cute so we started talking then we exchanged numbers and i told him i will never send nudes give blowjobs and stuff like that im not like that and he said he was never gonna bring that up in the first place he thinks im perfect i sent him pics of my stomach with a shirt on to let him know im fat in person and he said im fine im not fat and he seems like a really good guy! He asked me to call him because he wanted to ask if we could hangout if i want and i said yes! So were hanging out tomorrow and hes picking me up and were going to a park close by my house but im really nervous ive never gotten in a random teens car before bymyself and i wonder what if hes a crazy driver? What if hes not real? What if he rapes me? This comes to my mind no matter what its not just him but i wanna do it and he thinks im cute what do i do?
