Night shift

My husband got a new position and now he works nights . Nights were the only time we really had to have sex besides during my sons nap time ...... and my son has recently started slacking with nap time which doesn’t really matter Anyways because now all my husband does is sleep during the day which I completely understand he’s tired he’s been working all night ...... but like he chooses sleep over the only time we have to be able to have sex and I’m going on two weeks no sex ..... like I’ve tried I am completely naked when he comes home and I’m all over him and he just rolls over to sleep . Or my son wakes up . I’m just at a loss here :/
