My sex life with my SO is dead

Lately we haven't had a lot of sex, it happens  MAYBE once every week or two. And I feel fine, but my SO has made it clear this is not the path for him. I feel bad because everyone has sexual needs, and when he wants it I ussually don't :/ I don't know what it is but i would so love to have great amazing sex... But my drive for him has pretty much died and it makes me feel really bad because I still love him to death but sex just isn't what it used to be anymore. The worst part to me is we are still pretty young like 20s
