I can accept that, but I would suggest that if a person has a secret they worry would end their marriage they should reconsider who they are marrying rather than deceive their would-be spouse.

Ultimately our choices have consequences. Renting your body for sexual acts on camera should have consequences. We can't simply be irresponsible and expect others to accept us regardless. I believe that to each their own, but my personal reaction, as requested by the op, would be a grave and extreme one in finding out, by no admission on her part, that my wife was let a large number of strange men use her for sex and paid her for it, on camera, and covered it up.
People can put their past behind them, that's fine, but part of doing this is reconciling how it affects one's future or the people they care about. Hiding it or pretending it never happened didn't help this poor guy, he found out, and if I were in his shoes I'd be crushed.
