My boyfriend feels inadequate in bed compared with my previous lovers

We were best friends for three years before getting together and I told him about the men I was seeing. Now he feels he is not satisfying me but I love him as he is My boyfriend and I had been best friends for about three years before getting into a relationship. During this time I had told him about other guys I was with and now, during sex, he feels inadequate. I don’t know how to make it better and talking about things just seems to make everything worse. I have such a low sex drive and
