For some context, this happened about 15 years ago. I felt a lot of pressure from the media to date, kiss, and have sex while still in high school. Teen movies about losing your virginity were pretty popular at the time but the internet wasn't developed enough yet to know what people my age were really doing and thinking. The closest you got were teen magazines which also pushed sex.
Nowadays young people are much less likely to drink and more likely to stay home. I don't think our culture has caught up with that. It might feel like everyone is kissing or having sex but there are lots of people that aren't. It's probably going to be even less common after quarantine is finally over.
There is nothing wrong with you if you haven't kissed anyone yet, it's normal.
Don't agree with the wording, but, yes, it's not as big a deal as it seems. I don't advise the bible, but do read a bunch.
