They don’t live in a porn vacuum. They absolutely have relationships outside of their job.
Yes, sure. I agree. But I doubt they do have more experience and/or knowledge in this field than the average person. Teachings how a relationship can improve are limited, because its quite unpredictable due to the mix of cultural, individual and social norms.

A lot? Some of them may be more or less famous and therefor a little different when in public, the reputation of the industry is rather bad, the actors and their relatives are subjected to shame, hate or similar. Also most of them have varying sex partners. If we put them on a list of deal breakes these are maybe one of the ones.
On the other hand someone might worry more about other obstacles in a relationship like spend too much/little time together, lack of or bad communication, trust issues, to be an equal part when it comes to care, housework, finance or too much emotional, material dependence. These are way more common I think and if you are able to compromise regarding these “inside” things you have a solid base to handle the “outside” things more easily. The advice of a porn actor is only helpful if all parties agree that all possible conditions inside a relationship could be ranked and are being ranked without contradiction.
Neither do I. It feels like you think I value them less as a person than others. I do not. Do we have a misunderstanding here because of my grammar or another barrier related my english skills?
