Think I’m turning into a prude 😂

This is a lil weird. so I’ve had one boyfriend-ish not even rlly. I’ve only had my first kiss... but I’m 15 on 16 & all my friends have and talk about sex all the time and I’m the only one who has done absolutely nothing. Not that i don’t want to. I just don’t know how to initiate it or who I’d even do it with because I’m so picky and turn down everyone. So the problem isn’t who but how and when bc i don’t want to do it wrong.
