Another idea
A straight religious person swaps with a gay person. They could either keep their gender and swap their relationship or they could be a woman who gets swapped into a gay marriage or a man who gets swapped into a lesbian relationship.
If we do a lesbian one I would like the guy to get swapped into the feminine side of the relationship rather than the butch one. Or he could be butch and then feels that a gets to keep a sense of his masculinity if that makes sense. Oh and vice versa with the gay couple
