PENIS REDUCTION 😢

Well my fiancé is well endowed, I'm not complaining it just seems we've hit a bumpy patch in our sex life. He wants to get a penis reduction, I love his size and girth but he is bent on the fact that he possibly could be hurting me in the long run and that I'm not able to perform such acts as deep throating his penis or committing to anal. I've tried everything from numbing solutions to even being black out drunk, nothing seems to help. I need help, tips or anything that could point us in the right direction.
