Most pornstars get married like everyone else. A lot to people outside the industry too. These marriages often last unlike some within the industry. Then again it a lot different situations outside too inside the industry. They start families too like many other people.
I believe most people in today's world see the adult industry as what it is a job or another form of entertainment. I've never seen any laws anywhere that says a couple has to be married to have sex, take their clothes off or even do this in front of a camera.
They have the same feelings as the rest of us. They even play that risky game called love like us too. Falling into it and out of it. Been the one doing the hurting or been hurt by someone who you shared your inner most secrets and feelings with.
I'm amazed at some people that seem to think that people in the adult industry are robots or something. Emotionless shells that are just wheeled out of some box, do a scene and then put back into the box till the next one. Instead of just jacking off to a adult video have look at the behind the scenes feature. As well as some of the interviews and the odd documentary that comes up on them. Then you'll see they live everyday lives like the rest of us. Yes some are what we'd call weird, but so could your next door neighbour who workson a factory line.
Their people just like us, not robots.
