so guys a new breeder and trying to see some lock photos and kinda just general help

so i have put them together a few different times and every time i come back and its a mass of snakes( him inside of her-- tails in the mess cant see them.

Today same thing but i want them they lined up and hid.

Should i assume they locked ??? if so how long to i want to leave them together?? over night? longer??

Will she start refusing him? until when should i keep introducing the male( lol until i see eggs)

Thanks
