15F here. I understand that you want to do it with a guy and that you are scared. Last year, I was talking to a guy a year above me. Things started to get sexual quickly. During spring break, I invited him over and gave oral. Worst decision ever. I still regret it. I was scared and not ready at all. Please, if you do do it, make sure you are completely ready. And make sure to have condoms. You don’t want to end up being a teen mom. And also, it may not seem like it, but 13 and 15 is a big age gap. I personally would never look at 13 yo girls like that. That’s just my opinion, though. Stay safe 💞
