Question for couples...........

*Update - done one of these recently - amazes me more couples dont want this "service" ............So, leaving cuck/bull adventures to one side...........Having spent much time in the UK and Europe why do so many couples shoot "selfie sex" when there's a willing number of guys happy to film them something decent? Done this many times for couples abroad and some want you involved but many don't so couples what is the reasoning for holding back?
