A lot of the parents in the r/deadbedrooms sub don't agree. (I am not a biological parent nor did I raise kids with a partner so I can't speak to it.)

That's probably because they weren't very compatible in the first place and having kids made that worse, or one partner has been left with the greater workload (if women have to mum ther partner also they're not gonna want to have sex), or their relationship has changed because kids will stress your relationship to the max.

I have a toddler. Still have sex (much less often but still happens a few times a month at least).
