So perhaps he just likes to watch...? 
I guess (hope) you mean in attitude rather than body and looks? 
Seriously, though, his angst came across as very genuine to me. Seems to me he encouraged her because she was so repressed and now she really likes it, he's no longer sure...!
Before replying I had another look at her AW and website.
If she dressed up in susies and stockings and would do anal, an old bloke like me could probably give her a good pounding from time to time, maybe bent over a table.
But if I was in her hubby's shoes I would want to play with some of the younger talent when she does porn shoots with other ladies. Also I would take her to parties like the one I went to last Monday, leave her in room to have multiple shags with young studs, while I did the rounds playing with the younger better looking talent, without having to pay anything, other than cost of petrol for the Jag on the trip up to Sutton.
