I want to lose the ability to finish with a woman [everything ok]

A huge fantasy of mine is being conditioned to slowly lose the ability to cum over women. Slowly having my mind broken and reprogrammed until I completely dependant on a man to make me finish. It's similar to a conversion but I want to still have interest in women but just not be able to finish with them. Anyone else have this fantasy or is there any online content that specifically has this?
