have some uncommited fun
not seedy... just fun, and enjoy being single, having loose relationships, and dont mind getting into relationships you know wont be forever.
got loadss of people getting engaged at 16, 17, 18... and everything else, if it makes you happy, and its going to last, then go for it!
however, look at the theory, you start having fun when your 16... have 10 years of fun, and then get married, and have 60 years of marriage
you dont have to get married to the first person you conect with
