I've been feeling this way too. For a while after I didn't even want to be touched besides a hug. It got a bit better, but has gone back to disinterest. For me I know it's partially because my daughter has started sleeping worse again. I never know when she'll wake up. So there is a worry of her waking while anything is happening. That and I'm mainly valuing sleep over physical intimacy betong cuddles.
That’s how it is for me too. My partner thinks I don’t like him that much but it’s not that. I just don’t ever feel up for it
