For a deep dive, see Pope St. John Paul II's Theology of the Body[1] and the late Fr. Paul Quay's The Christian Meaning of Human Sexuality[2].
To lessen distractions from the cares of daily life, retreats are usually conducted away from one's domicile in some peaceful setting (mountains, coast, etc.), at a "retreat center" or some facility that provides sleeping quarters, bathrooms, meeting space, and a refectory. To make the whole exercise cost-efficient, a retreat is usually conducted for a small to medium-sized group, rather than for just one or two participants.
In the context of religious institutions, it is a fairly common practice to organize retreats for persons who are finalizing their preparations for a change in state of life, e.g. going from single to married, lay person to ordained, student to graduate, etc. The topics addressed at such retreats usually pertain to that change, with an aim to help participants better prepare internally for the obligations and challenges ahead.
[0] Not sure what it would be called in the US but something very strictly Christian where you cannot do anything on sunday, not only not work, but also not drive cars etc and in are not allowed to have (own or use) TVs, radio's, computers and have special schools schools which teach them this kind of thing. Thinking (yes thinking), at any moment, about anything that is not allowed, will land you in hell. The ordeal made me an atheist at a young age, but I remember the teachings well.
Thing is, I'm not particularly religion and neither is my wife, but our family insisted we get married in a Catholic church so we had to go through with it. So I opted for the retreat because it got it over and done with in a weekend.
That's my point. Christianity has long been very pro-sex, just with your spouse. As I said, you could be sued for not having sex with your spouse.
>Also, as someone who was raised Catholic it was very clear. If you're not doing it to procreate you are sinning.
That is totally incorrect. You aren't allowed to prevent conception, you need to "let god decide". But there's nothing suggesting the purpose of sex must be procreation. Again, there's a spiritual and emotional side of sex that is seen as vital.
Someone can say it has an emotional aspect all they want (and they do, and it's true) but that doesn't stop the other part from being true too.
Note: I have a child and I love her more than anything. Buy saying you can't do anything to prevent pregnancy and saying the only way you can have sex if there is a chance you procreate is the same thing (unless your physically incapable).
No it is not. At all. Saying you can't barf up your food after you eat it is not the same as saying you can only eat solely for the purpose of nourishment. You can still eat for taste and pleasure. You just can't prevent yourself from getting the nourishment that goes with it.
>Buy saying you can't do anything to prevent pregnancy and saying the only way you can have sex if there is a chance you procreate is the same thing
Which has nothing to do with the subject. You are confusing intent with outcome.
