how to ask husband if I'm good in bed

hi ladies! my husband recently told me that I sometime accidentally scratch him with my teeth when giving head. now I'm feeling self conscious and want to ask him if I'm good in bed... how do use word it? what would u say? I think I've got the teeth situation under control, but I want to blow his mind! I want to know exactly what feels best to him so I can do it all the time. he can be kinda hard to read. he always tells me how tight me p**sy is, and that i made him cumm quick, so I'm not too concerned with that. do u have any go to moves?
