My two pence (and this is not necessarily in contradiction with anything you’ve said): Don’t tie yourself to anyone who would make a good father or a tolerable companion if you don’t feel like really passionate about them, like you could make love to that person for the rest of your life.

Art, friends, family, work, study, hobbies… can contribute to the fulfilment of any other needs but Sex you will only have it with your partner (or on your own). Make sure you get what you deserve and don’t make a disservice to other person you will never feel deeply attracted to.
