Ladies, how to you like having your boobs sucked on during sex?

there are so many tutorials and even apps that show you how to go down on a woman but almost nothing on how to do it to the boobs instead.

till then please dont tell me to go watch porn, cause I hate it. I hate how they go straight to the nipple and suck hard making loud thundering noises like savages. hell even lesbian porn seems to follow the same regimen so I'm officially not trusting porn as a liable source. I prefer the love making way such as starting from the neck then kissing and caressing all the possible erogenous angles before making my way to the nipple.

but till then I'm open to other methods as well. so I was wondering if anyone can please explain how they like their partners to please them in this department
