Oral Sex and Christianity

I am sure that by just reading the title alone, many may automatically be put off.  But if you just bare with me, I am sure you'll find that there is method behind the madness.

A couple of days ago I was talking to a friend of mine,who is married and she discussed the fact that she did not feel comfortable giving and receiving oral pleasure to/from her husband. Her reason behind this thinking is that; 'it is ungodly'.
This was much to my surprise because I was of the opinion that if you are married,everything goes. When I say everything,of course not swinging,and other means of pleasure that allow other people into your love making sessions.Some may disagree with my opinion but I'm approaching this,as I approach everything; with a Christian world view.

This conversation with my friend really got me thinking, as prior to that I had no idea oral sex was even an issue for married Christian couples. I spoke to  Coach Abbey G, a London based Christian relationship counsellor and Pastor Fortune Obasi of Blessed Assurance Bible ministries,Rivers state,Nigeria: to get a varied and perhaps clearer perspective on the issue.
' I believe as Christians we need to be more open about such topics, instead of being open to ridicule and judgement. Communication is key and essential,' advised Coach Abbey.

'Whatever will make your marriage last is what you should do, as long as it's done with mutual consent and love,' suggests pastor Fortune.

Coach Abbey considers health (risk) to be another factor that may contribute to people's unwillingness to give and receive oral pleasure. 'Aside from personal/religious reasons,some Christian couples are also concerned about the link between oral sex and mouth cancer,  and all other forms of STDs.'

In terms of whether oral sex is right or wrong(godly or ungodly), Pastor Fortune pointed to 1st JOHN 3:20-21
'For if our heart condemn us, God is greater than our heart, and knows all things. Beloved,if our heart condemn us not,then have we confidence towards God.' In other words,if you are at peace with it then go ahead but if you feel uneasy, seek the Lord and communicate  openly with your spouse to reach an agreed end.

Well, you've read some of the opinions, what do you think?
