How do I get husband onboard?

We have a 5month baby and my husband doesn’t realize but he’s been really absent in our sex love. We only have 1.5week(s) together in a month due to his work.

I mentioned wanting to have some foreplay and he asked if I meant like me being a maid and stuff like that and kind of laughed at it. Stuff like that turns me on and I would like to get the bedroom a hot place again.

Is there any kinky things to turn the bedroom into a hot place to slowly ease him into trying things like this?

We have normal sex, me on top and from behind. That’s about it.
