Whilst on a flight from Germany to Hong Kong a man in the next seat started up his laptop and was oblivious to the fact that his hardcore porn could be seen and heard by me and people in the next aisle. As a woman travelling on my own on an overnight flight, this made me extremely uncomfortable. I raised it with the purser - the man was moved and spoken to, apparently. As for the countless times I've witnessed this on the train, there's been no hope of anyone in authority sorting it out. You either have to move seats, say something and risk being verbally attacked, or seethe quietly until your stop. I'm not anti-men, anti-sex or anti-porn. Yet whenever I've raised this issue in the past, there's always someone ready to call me out for being a prude. I'm not. I just don't think porn has a place on public transport, or in any areas frequented by the general public. Annie G, UK
