Pain tolerance/ enjoyment

I would say that I enjoy pain to a higher level than most and my kink does go well with my partners, exept that he likes beeing really rough. I would like to be able to give him what he wants, but at a certain point ist just not enjoyable for me, because of the pain.

So is there any way I could build up my pain tolerance to also enjoy beeing hadled rougher.

I know he enjoys sex but I just want to give him more than I am able to at this moment.
