Here we get into the problem of definitions. Relationships are complex in your view people can be monogamous but have foursomes with sex workers - I would call that 'monogamish' which is a type of ENM.
Also seems to be Netav's view. I prefer to think of SH as someone who wants a nesting partner because he has a strong desire for home and hearth. And some fun at the local druid grove if Tav is okay with it. I think the FR equivalent of Saturnalia is mid-winter fest and something tell me SH will want to attend.
