As a rule sexual failure is a neurotic symptom. The upshot of that being that it is by no necessity a permanent deficiency.
In the case of this sexual problem, I would have to disagree with you. It is normal for a woman to not have much sensitivity within her v****a. Most women have only have sensation close to the opening and nothing more. I think the issue is more to do with expectations than true neuroses. The OP just needs to adjust her expectations of intercourse to be more realistic and to use alternate means of stimulation-like ribbed condoms during and clitoral stimulation before, during or after.
