Hello
Welcome to healthcare magic
as per whole description about your sexual life with your wife and the detailing explores whole thing about status of sexual excitement of your wife.
This condition clearly shows its purely psychological reaction. But she also do not know, may any hidden thing works in mind, but she also do not aware about that.
Now your point related to
hormonal disturbance. I like to tell you one thing is that whole sexual act is depends on mind set only and after getting pleasure and excitement hormone secretions works it self.
But Mental status is a switch to on and off for hormones, lubrication, secretions, and reaching to orgasm.
Talk, relaxation, discussion, love, faith, foreplay, love without sex, act without sex may leads her more relaxation.
Do not try to sex forcefully and do not go as trial and error way.
GO forward with patience and gentle way. DO not keep topic about sex in front of her and go forward step by step.
It needed
counselling.
Its not a case which needed any medication. For this you are only a medicines, which make effects if given properly, else too much side effects too.
Can also get online counselling too.
