Theres a difference between "lying" and keeping private things private.
Just because he's her husband does not entitle him to know every detail of her life before him, nor does it mean she has lost the right to keeping private parts of her past private.
For the record, I don't recall there being any "lying" going on. She simply said she doesn't like to give them, which she now doesn't (AKA it's the truth.) It's immaterial as to why she now doesn't like to give them - whether its because she lost the desire for it, or she never actually liked it and was doing it for unhealthy reasons (like being pressured by men) or that she simply doesn't like it with her husband for any reason which is wholly appropriate (maybe she sees it as an anti-intimate act, because of her past, and she actually wants sexual intimacy.)
Bottom line is...
- Husband is not entitled to them, no matter how many she gave in the past.
- Husband is not entitled to know anything from her past she feels is private. Keeping private parts of you private is not "lying."
- She is entitled to refuse any sex act for any reason at any time.
I can't believe this has to be explained.
