Sofia Lose, what hardtobeme is mentioning is the type of thing that subtly messes your mind up. JW's live in a impossible world of the idea of sexual purity that just can't and doesn't really exist. Witness think the world is sex obsessed, in one regard they are as that is what people want and it sells as they say, beyond that, witnesses are WAYYY more obsessed "don't look at this, "don't touch that", "don't think about that" "get married or no sex for you" They talk about it at the meeting to no end! Pornography is mentioned in every part, or homosexuality, or adultery. They ARE obsessed.
And marriage is another institution like religion, its f%$@ed up, and by that I am not saying that monogamy is = to marriage, you can have one without the other, but it exists as a system of consequences and control. Their overall attitude towards sex stunts people. You cannot really know yourself waiting, then marrying someone you've never screwed, especially when you are so young, you don't know what's going on yet.
