New sex laws

Before robot sex, we all (including movies) thought virtual sex would be the "in" thing.
What if there was a law that uses VR sex without losing the human element?

Tri Sex Marriage
This law is meant to cut down on sexual experimentation in reality.
When the three desired partners meet (must be 2 females and 1 male or 2 males and one female), they sign some sort of agreement that allows the three to marry as long as neither of the partners cheat in the real world.
If any one of these partners is found cheating on his or her partner, all three must break up, which gives a better incentive for the three to stay together.

The above rule does not apply to heterosexuals.
Robot partners will be available to heterosexuals in all US states.

The virtual cheating law will also promote consensual video voyeurism, virtual exhibitionism and public masturbation (to children and teens as well as adults), virtual incest, and cyber paedophilia, which may actually be safer than violating a real child.
Virtual mother/son and virtual father/daughter sexuality (what I call outcest) will also be allowed.

All this by the early 22nd Century.

Do you think this is likely to happen given the recent argument over gay paedophilia and even legal incest?

Hey, they've already started with the Marriage Equality Bill!
Now just give bisexuals polygamy status (with legal provisions) and we're all set!

Soon robots will get into the picture (maybe by 2030).
