Sex after Surgery

Hi girls im 19 and had this emergency surgery they removed my right ovarie cuz a cyst exploded and caused inner bleeding. Almost died (Thx God I survived🙏🏻) Now i know i cant have actual sex till my insides heal thats kinda 4-6 weeks but my bf wants to know if we can make Oral. He is really over protective so he doesnt wanna do nothing it will hurt me. I think that it would be ok but if anyone knows please!!
