in my experience, porn actresses are hard to please, NOT SEXUALLY as their act is just that, an act and they are mechanical and without feeling, but in the social scene
They like the high life and the expensive stuff, they are big headed as they think they really are Hollywood stars, they go through cash as if it was going out of style.
MPs could be honest and giving but the hard core ones are cold hearted and disengaged
If you dated either one at some point you are down for hear break, if you simply see them casually you are in for good times expensive with a porn actress, not so much with an MP
