Do octopus reproduce sexually or asexually?
The male and female reproduce sexually. The process varies by species. When octopuses reproduce, the male uses a specialized arm called a hectocotylus to transfer spermatophores (packets of sperm) from the terminal organ of the reproductive tract (the cephalopod "penis") into the female's mantle cavity.
Why do octopus eat their partner?

Octopuses can sometimes suffer from autophagy, or self-cannibalism. That is what is described as "eating its own arms." This is caused by stress.
