My wife used to watch porn with me occasionally & the sex was great but she wont anymore. any tips on how to get her to again. Are there any huge cock movies that have a story maybe that would work instead of just pure sex
If she doesn't want to, she doesn't want to. Maybe it just feels wrong for her, maybe there is some other issue like she doesn't want to rely on that for good sex.
Really the only thing you can do here is talk to her. Ask her why she doesn't want to. Let her know you really enjoyed it and you want to understand what has changed for her and see if you can maybe do it again sometime.
But any attempts to do it in a round about way will fail - not to mention that it'd be completely transparent what you were doing and may well just piss her off.
