Well, begging is certainly one way to get sex.
Seriously though, I find it hard to accept that with wives like her, the husband could...well, not show any interest? Why even marry her then?
I suppose it's just a cheap way to get us to not sympathise with the husband and just accept that she is currently cheating...
I would feel bad for the husband if he wasn't a guy tired of his wife, not even praising her body. tsk. She is better off with the guy that loves her and her body. that is if the guy really love her and is not just using it to get into her panties.
