When I announced I was moving to Paris to live with a man I’d met in the Bahamas four weeks earlier, no one who knew me was surprised.

They had no shortage of opinions — “You barely know him,” “You barely know French,” “You know they don’t have Krispy Kreme in Paris, right?” — but shock was not the underpinning emotion fueling most of them.

My dropping everything to move thousands of miles away into the arms of someone whose middle name I didn’t know wasn’t terribly uncharacteristic. Not that I’d done that before, but I did tend to throw myself into exciting new endeavors with a somewhat, ahem, aggressive speed and unwavering confidence. And in my early 20s, that certainly included romances with near-strangers.

But according to the New York City-based sex therapist Stephen Snyder, the author of the forthcoming “Love Worth Making,” that desire to jump into new romances headfirst is only natural.
