school expectations

Hi!! I'm 15 and I still haven't kissed a guy or gone out with one, I feel like that's weird because pretty much everyone else in my year has and i feel like I should but the thought of snogging someone scares me because I don't know what to do!!! There's this guy that I've liked for a long time and recently this other guy started to like me and I could have a chance of being with him but I feel like my crush is holding me back. He's not holding me back but I'm holding myself back because of him and I feel stupid😂😂 but yeah just wanted to post this out here If you have any advice help!!!
