I haven't experienced such things, but it's nice some scientists are willing to take the plunge: a researcher from the Nerve think-tank describes going to a spa which offers "happy endings", which sounds far more pleasant than anyone could have explained; just the ambiance sounds like a fun time, without the extracurricular activities. If only the writer had read an article like this before going, he'd have been far less nervous. Still, it's a sample of one, and I'd probably end up at a creepy massage parlor, run by people of indeterminate gender and lack of running water.
