IS IT Over??

So apparently for the past few weeks I've been wondering that I'm almost at that age when I'm out of school but not 18 and still getting fomo that I never held hands..let alone holding hands..I've never had a proper relation with any girl outside of family which is really odd idk why...I haven't really tried and put efforts but still have seen many guys doing it without efforts..I'm not saying that it's magical and if they didn't i shouldn't..it's just that I've never experienced which can make me more awkward as I grow up...I'm actually not really bad looking infact a total opposite touch wood but still it hurts cuz bp ruined many things yknow..I've made eye contacts and had small talks but nothing serious...so is it true that it gets better with age or I'm missing out on something which is done now
