the whole dating thing before uni is *largely* just playful and not going to go anywhere - my relationship is one of very very few that has made it to week... 7 of uni? most broke up within the first fortnight
the thing is , you're young and it is unlikely that you're going to meet your ideal partner at 16 , or that they have developed enough for you to realise it at that age. maybe a childhood sweetheart will become ideal - it's all about development
don't worry about what everyone else is doing , the majority of my friends haven't had serious partners and tbh , up until around six months ago , the majority were virgins. look after yourself and what you want , and make sure you're happy , and there's nothing else to worry about
