I don't think this behavior makes him a misogynist, but it does speak poorly about his behavior, especially around sexual autonomy.

You will definitely want to have some serious discussions around this. Let him know how his behavior isn't cute or endearing, but makes you feel objectified and disgusted. He's probably feeling more ignored with the baby and is trying to initiate, but doesn't have a good way to do it and isn't respecting reasonable boundaries.

This behavior unfortunately seems to have a bad feedback loop built in. He wants more intimacy, so behaves in a way that in the past was taken (at least by him) as flirty and fun. You see the behavior as boorish and it kills your desire for intimacy. This causes him to ratchet up his boorishness.

It might also be a defense mechanism on his part: if you reject him, it isn't him you are rejecting, but his crude joke or behavior. So he gets to ask for intimacy, but doesn't have to feel rejected if he doesn't get it.
