Have never understood the watching of porn when in the company of other men!!!! surely it's a solo activity?
I think it tended to stem from the number of videotapes and VCRs ..... in the dim and distant past, if you were on some sort of standby, you'd probably take over a mess TV room and you'd watch whatever the general consensus determined. You might well have your own VCR at home, but on standby in the mess you were reduced to 'A TV, A VCR' between the lot of you.
I even recall the whole crew going to the 'Astra' to watch some soft porn epic on SAR once. It was either that or re-reading 'Punch' all day, and on any sort of standby you all stuck together in case of a callout.
Most films seemed to be rated more highly if they included plenty of unintentional humour.
Having said that, the average Nim crew would happily watch something like Red October in preference - in later years, to my horror, the younger siggies seemed to rate 'Corrie' as the number one TV attraction, so I retired and bought a tartan travel rug.
