I've enjoyed the series and all the ones that came before..
I'm sorry but you both came over rude and arrogant, commenting on performance, duration, size of mens manhoods.
As fabio said, there is a lot of trust involved in swinging and I too would be mortified if comments were made about me.
Ok I would expect you to talk between yourselves about it, but to make comments like that to the camera crew, and after the edit, STILL allowing those comments to go on general release IMHO is wrong.
Throw away comments like (i'm not trying to quote the exact words) "thats how english girls do it" and "well i made her scream", well I'm sorry they sounded arrogant.
There was a little bit 'edited'

where the american lady was going to comment on your performance.........I wonder why that was deleted.
Although the program was very well made and seemed to put over a balanced view IMO it also put over the view that english swingers will judge you and find you lacking.......don't go there.
You are probably a really nice couple, nerves, being abroad etc etc may have made you come over wrong.......but there was no excuse once you were home and allowed to have decisions in the editing (as you said you did)
I apologise if you feel offended by my post....but after all it is just my opinion
