Different work schedules

He's a teacher and I work in the medical field. He gets off to porn a lot and normally that doesn't bother me. But most days he's already gotten off before I get home. And obviously isn't in the mood for fun with me. And I have no personal time to get myself off most days because I help put his kid to sleep on days he has his kid. Idk what to do I feel like his babysitter.
