Whether you’re travelling with friends or flying solo, nothing says vacation like hooking up with someone new in a strange land. Having dipped into the summer fling once or twice myself, in Italy and New York, I know the allure of a quick tryst is hard to beat. It feels exciting, effortless, and a little unreal. But fleeting romances are just that, temporary, so do not get too attached. The chemistry may be instant, but the clock is always ticking.
