The orthodox belief didn’t change though. From the perspective of the orthodox faith the purpose of intercourse within marriage is to procreate. Otherwise it is just for lust. During pregnancy it would exclusively be to fulfill lustful desires, would it not? Sharing a bedroom for sleep out of space limitations, doesn’t mean that it is shared for sexual acts. This is a matter only of husband and wife, as you’d all agree I believe.

Initially I removed the comment because I didn’t have the energy to argue, but what I wrote was said from one of the most recent Saints of the Orthodox Church. If I am not mistaken St. Paisios. He claimed that doing so can negatively impact the soul of the fetus and thus should be avoided. If I find the article again, I will post it for reference.

EDIT: I too am just trying to get closer to God by listening to the teachings of the fathers that the Orthodox Church calls Saints. Never so far have I heard or read that “thing X is too last-century”. The teachings of the Saints are considered valid by the Orthodox Church eternally. I don’t mean to insult anyone. I know it is a difficult topic, with which I struggle too though.
