Read the sticky and get to work. It's the only consistently good thing about the board.
If you are having trouble with the books suggested you may ask for alternatives, though many are already suggested in the sticky.
/co/ also occasionally has art threads. These are sporadic in nature and have only recently made a comeback.
Just for you OP. Keep on looking at it and put it on paper with one hand.
Start out small, cute, and with very little detail and then just keep drawing them. Tits aren't too difficult once you get the hang of them, they're adorable little things too.
Boob tutorials are kinda silly. Every one of them is still somehow based on the artists own personal preference. Boobs are just as varied as human bodies, they come in every possible size and shape. Also saying what the "correct" way to draw them, and telling people the "right" way is the only way to draw them is sort of like saying art should be only classic Realism, because its the most "correct" depiction of the subject.
Of course understanding how boobs work is an important knowledge to have as the base when drawing them, your own way.
