Are there porn actors/actresses who actually like what they do/have done?

I have read a lot over the years about exploitation in pornography and people getting into it under duress. I have seen comments from many people who regret their involvement and want their content removed years later.

But there have to be at least some people who enjoyed it (as much as anyone can enjoy a job) and have no (or just a few) regrets about it. Are there people who have been open about that? I just cannot fathom that an industry exists where no one is actually content.
