I wan't to have sex and he doesn't. Does a man's drive also change post his wife's delivery?

physically, there is no connection how his drive can change after pregnancy and childbirth, but of course with the change in routine, it is possible he is tired too. if there is a young baby in the house, it could affect his sleep,and also increase stress. also, some new dads are too careful and conscious about not hurting the mom too soon after childbirth, and are also not comfortable doing it initially with a new baby in the house. do talk to him and see what is bothering him, and help him ease it out :)
