In other words, Leah’s is a generation that has been raised with the concept of sexual freedom and without solid guidelines for how to make monogamy work.That some brand of non-monogamy would appeal to large numbers of them is thus unsurprising.I was very unsure of all that.” Leah, however, forged ahead. Her one concession to upstate New York’s brutal winter is a Syracuse sweatshirt that she can quickly jettison as soon as she enters any party.

One of the things all the therapists had noticed over the past few years was “that couples – and these are younger people, twentysomethings, maybe early thirties – are negotiating what their brand of monogamy can be.

They are opening up to having an open relationship, either in totality or for periods of time.

By the end of their dinner at a small Italian restaurant in New York’s West Village, Leah is getting antsy to part ways with her boyfriend Ryan, so that she can go meet up with her boyfriend Jim.

It’s not that she means to be rude, it’s just that Jim has been traveling for work, so it’s been a while since she’s seen him. As her “primary partner” and the man with whom she lives, he is the recipient of most of Leah’s attention, sexual and otherwise, but he understands her need to seek companionship from other quarters roughly one night a week.

Tonight is one of those nights, and soon Leah will head to Jim’s penthouse apartment, where the rest of the evening, she says, will probably entail “hanging out, watching something, having sex.” “She’ll usually spend the night,” Ryan adds nonchalantly, which gives him a chance to enjoy some time alone or even invite another woman over.

He doesn’t have a long-standing secondary relationship like Leah (“I’ve actually veered away from doing that”), but he certainly enjoys the company of other women, even sometimes when Leah is home.Or, more specifically, that going outside the partnership for sex does not necessitate a forfeiture of it.“I was at a practice where we would meet every week, six to eight therapists in a room for teaching purposes and to bring up new things coming into therapy that weren’t there before,” says Lair Torrent, a New York-based marriage and family therapist.In fact, Leah and Ryan are noticing a trend that’s been on the radar of therapists and psychologists for several years now.Termed “The New Monogamy” in the journal it’s a type of polyamory in which the goal is to have one long-standing relationship and a willingness to openly acknowledge that the long-standing relationship might not meet each partner’s emotional and sexual needs for all time.“I remember the first night, I was telling him about my difficulty with monogamy,” she says.
