Hi,
thanks for using healthcare magic.
I have gone through your available history.

consult sexologist to have proper evaluation. I do not feel any physical abnormalities in both of you but you need sex education for better enjoyment.
Pain to your wife might be because of faulty position or inadequate lubrication.
meanwhile you can surf the various sex position on internet and exercise masters and johnson technique for better control over ejaculation.
thanks.
