A Godly marriage and breastfeeding. It's what God made your breasts for.

First, I want to clear up some misconceptions of what ANR is.

Adult nursing (ANR), Adult breastfeeding (ABR or ABF) are all umbrella terms. The simplest way to understand ANR is, any time the breasts are orally stimulated by another adult. The couple is engaged in some form of ANR. Whether or not she is lactating.

The number one reason most people are into ANR is for intimacy. They also find it as excellent way to reduce stress, anxiety and depression. Some women get into ANR as a way to reduce breast cancer risks. yes! There is research that proves this works. You can find it by searching for "benefits of breastfeeding" and "benefits of stimulating the breasts".

Though in theory, a woman doesn't have to be lactating to have some of the advantage of this. But a lactating woman will have by far the greatest risk reduction and benefits.

Some get into ANR as a way to help reduce and manage weight. Most breastfeeding women do loose weight. The idea is that a lactation woman burns between 300 to 700 calories per day. Though I personally think it's more of the placebo and lifestyle change that helps them.

Some are into it as a sexual alternative like those with ED or other sexual issues. Even as a form of abstinence.

When a new mother is having trouble bringing in the milk. Some doctors and lactation consultants will suggest that the father finish orally draining the breasts after the baby is done. Same goes for relieving clogged ducts.
   
Those of us in ANR find that ANR also preps the breasts for a new baby. Making breastfeeding a lot easier. This is because the breasts are use to being orally stimulated. The milk comes in easier and is less painful. Though there is some caution on this as well. Because too much stimulation can cause premature labor.

There are a lot of emotional benefits as well. Such as, some use it as a way to cope with stress, depression and anxiety.

People get into ANR for a lot of other reasons and a for a lot of other benefits.

ANR is supported in the bible.
Proverbs
Songs of Solomon
Isaiah

This shows ANR has been around for a vary long time and is normal.

There are those who get into ANR with some fetishes such as Lactophilia or infantilism. This is what media likes to make people think ANR is. To be clear. ANR in itself is not a fetish. It is two adults expressing affection and intimacy for each other in there own way. But people like to assume Lactophilia or infantilism is ANR. They are not! But some of those people use ANR as a part of there fetish.
