struggling with chemistry

I have nailed almost all aspects of my life but im lacking on finding a girlfriend. This is not a major issue for me but i would like to get married early like 24(18 now). I am 5'8, know 5 languages fluently, i would say pretty well kept eg. (straight white teeth, gym, educated) and an avid sportsman(karting and football). I can initiate convos easily and they lead to positive outcomes and interest but they are never long term. I dont really mind being alone but i would really like some chemistry with people. I dont aim to be a ladies man or something but seeing some guys effortlessly hold conversations without boring them out is unique. I dont want temporary 'game' but am aiming to find someone long term and preferably not miss out on teenage romance. So boys help a lad out. cheers.
