I was on a vacation like some years back and i was travelling alone as well and the trip was planned for a week which was cut short by some train schedules to 6 days. I met a total group of strangers (4 people) in the train and we talked and ended up spending the 6 days together travelling and all. We rented a guest house for the days and on the last day we got intimate and left on our own ways the next day as if nothing happened. But the thing is i never saw them or even kept contacts and i didn't even feel a need to and i think they did too. We just could accept that we got intimate despite being total strangers and we could let it go. Is it natural to feel that it wasn't a big deal? Have you ever experienced anything like this?
