But with married people in pornography or prostitution , more often the spouse is another (active or former ) porn actor, stripper, or prostitute. It makes the relationship more even and takes out the sting if sexual epithets are hurled in an argument since the jibe applies to both parties.

Probably right.

Still don't understand knowing somebody else is "with" your spouse and being "good" with it..

Maybe I'm "insecure" in my masculinity....

Or just raised in a good household with loving parents.
