What if he really was your boyfriend. The unlimited amounts of money would be an advantage, and you'd never have to join the queue to get in anywhere. But there would be two security guards following you everywhere. Depends if the security guards where goodlooking too and if they liked threesomes.
Seriously, someone who has grown up with such an enormous sense of entitlement, grown up to believe that as a royal he is superior to normal people who work for a living, the ones who pay the taxes that he sponges off, such a person would be a right royal pain in the arse to live with.
