That might be some of the subtext in this article, which includes a variety of first-hand accounts from men who are married to porn stars.
An excerpt:
While you toil away at a conventional job during the week, your wife spends eight hours a day getting plowed by guys with nicknames like Thug of Porn. There are the indelible mental images. There is the awkwardness of explaining to friends and colleagues—let alone to your parents—what she does.
One guy in the article talks about how his porn star wife tells colleagues that she's "in a relationship" rather than married. She also rarely wears her wedding ring -- for fear of being typecast as a MILF, she said.
Would you ever be in a relationship with a significant other who for one reason or another couldn't advertise his/her attachment to you? What about with someone who couldn't publicly disclose his or her job?
