The Bible clearly talks about the two becoming one flesh AFTER marriage.
So absolutely my interpretation of Eastern Orthodox teaching is that AFTER marriage then you may have sex.
I don't see how a piece of plastic allows you to become one flesh as God intended sex to be. In fact in some cases you can see the perversion in it.
As far as the bedroom goes, that's between the man and his wife with the door closed. So long as it is natural and between them it's not the Church's business.
And in old time it was more then just “spanking” – it was “death penalty
” for not respecting parents.
And even St. John refere to it :
6. The wise Sirach says: Hast thou children? Instruct them, and bow down their neck from their youth (Sir. 7:25). But the Lord does not only prompt us with this command through the lips of His prophet; he even takes our side, supporting the fulfillment of this commandment with the fearsome punishment that awaits those children who do not submit to the authority of their parents: Every man who shall speak evil of his father or of his mother, let him die the death (Lev. 20:9). He punishes with death those who become guilty before you, and you look tepidly at these sins that they commit against the highest possible authority. They are rebelling against God Him self, transgressing His commandments, and you look at this without the least displeasure, without the slightest criticism of your children. What does He have to lose from their offense? Nothing. But you, why should you not fear for your own selves? For whoever abandons the Lord will never respect either his own father or himself.
