Okay, you’d be lying if you say you don’t notice an attractive man when he smiles at you. We all do. And it’s perfectly fine for your married (or boyfriend-ed) self to admit it. But a funny thing happens when you’re truly, deeply committed: you’ll think that guy is less
hot once it's clear he's an admirer. In a study led by John Lydon at McGill University, women (and men) who are deeply committed to their partners found an opposite-sex face significantly less alluring when told that the person had singled them out as a potential match
. It’s a protective mechanism; they might not even be aware of it. Meanwhile, women who aren’t very committed to their partners are just as attracted to a handsome guy when he comes out as a potential suitor. So if you’re in the habit of finding Don Juans equally (or more) gorgeous when they do something flirty, there is an upside: Now you've identified your own early-warning mechanism and can work on a deeper commitment with your partner.
