Cleared to have sex again but.....

My doctor gave me the green light to get my freak on. My husband and I spent my entire six weeks learning and exploring new ideas for the bedroom. My tubes are tied and all he can talk about is not pulling out but I’m afraid I want him to wear a condom. He feels like it makes no sense being that my tubes are tied. Anyone with similar situations? I’m too afraid and he refuses to use a condom.
