Multi-partner relationships are on the rise, and finding their way into the mainstream. Could this new exposure change the way we look at sex and families? Ian Jenkins, 45, faced death threats after coming out as gay while at university in Virginia. At that time, he could hardly foresee a day when he could live as an openly gay man with one partner, let alone two. But today, he shares a home in San Diego with his two partners, Alan, 43, and Jeremy, 37, (who are using their first names only for privacy), and their two children, ages three and one. All three men are the children’s legal fathers, their names on both birth certificates.
