The everyday lives of the non-monogamous

The Open Photo Project aims to reduce stigma about consensual non-monogamous relationships.

In one recent study from the US 21% of the study's participants reported having had some kind of non-monogamous relationship - but that number could be higher, owing to people not willing to share their personal circumstances.

The founder of the project and photographer Erika Kapin explains why she wanted to photograph their everyday lives.
