I know this thread was written almost 2 years ago, but I can't help but comment on it because I just happened to come across it.
I see so many people commenting and being judgmental...yet I have not heard one really use scripture that deals directly with the subject...what you are talking about is using words that we don't normally use in public because they are "sexual" words and therefore not appropriate. Do you think that talking about sexual intercourse or how it happened or describing the act was appropriate to say in public during biblical times? No. Yet, there is a whole book of the bible that describes Solomons love, his and her love making abilities.
Remember people this is the marriage bed, God gave myself and my husband ultimate freedom to do what we like with one another's body. Granted he should treat me as Christ treats the church and I need to love and respect him, but that's not restriction...that is true love and true freedom. Talking dirty is not bad in the confines of marriage, talking dirty is exactly what Solomon did. It's a way to express your physical desires or what is actually taking place or what you would like to take place. Just because you are uncomfortable with it does not mean you should judge someone else and make them feel guilty for it. As long as their words are not hurting someone else then it's fine.
Oh and using the "if you can't say it out in public then you shouldn't say it in the bedroom" thing, good grief...I can't rip my husbands clothes off and have sex with him in the middle of the street...good grief it's the marriage bed what's done/said in there should stay in there...have you know thinking ability?
I almost wonder if half the people that answered this questions weren't single, or if they themselves were in a unsatisfying marriage. I don't know and I can't judge them, but I do know that I have read Song of Solomon and it is beautiful, but it will make you blush as do these "so-called" dirty words.
Rethink your "righteousness" people, quit being pharisees and let this woman have the pleasure that her husband seeks to give her...it is not wrong, it is wonderful , righteous and yes, even beautiful.
