Yes! When my wife just gave birth, she was a bit shy from sex for a while (about three months), but i got back into it by sucking milk from her breasts.
Maybe her milk is making you sleepy.
those are not points they are called nipples and babies use them as a way to suck milk from the mom's breasts
There are no side affects to the sucking or kissing your girlfriends breasts.
They want to feel sexual, and they could want some milk.
Newborn babies put their mouths against the nipple on their mother's breasts. Then they suck the milk that flows.
How do boobs work? well when we get older, we have milk inside out boobs. and when we have children you can let them suck your nipple and milk will come out. that's the simplist way to put it. :D
they turn yellow
Yes, of course!
That is how babies eat.
We can grow big breasts by doing sex with other boys because they suck our breasts.
If you think so. It's your breasts.
The breasts are the upper part of the chest. The mammary glands give milk. Chickens have breasts and they don't give milk. Many sea mammals have nipples to give milk, but, they don't have breasts.
