Does open relationship really work?

[Bowyn Aerrow]

Open Straight Relationships.

So yes those exist.

As to why... that varies depending on the couple.

Does it work? That varies depending on the couple.

Its one or both jealous? That varies depending on the couple...

Well basically each of your questions is answered with 'That varies depending on the couple.'

To be fair we can question monogamy in similar fashion. Does it work? Not really, most people end up having more than one monogamous relationships, or even more than one marriage. even in mongamy there is jealousy and mistrust and all sorts of issues.
