Oral sex in Marriage: Biblically Sinful or Not?

I came across this on facebook.

"Pls let's discuss: Oral sex between a couples is a sin and should not be encouraged so said my pastor. My People,this is the bomb shell I heard today during service and I'm still dumbfounded. According to my pastor,sex between married couples according to God is meant to be penetrative and not mouth and hand satisfaction. My pastor's postulation also agrees with the message of Pastor G.O Adeboye that I listened to last year where he totally condemned the act and encouraged married couples not to indulge in such despicable act because it is a sin according. Church as we all know wield a lot of influence in this part of the world, though personally I'm indifferent because I live my life to please my creator and not to please my pastor. NoHBians,we r all adults here so let's Hear From You,what is your take on this controversial topic? Do u agree with my pastor's submission or do you have a different opinion?"

So I went on to share it on my facebook page and on twitter. Here is what some people on twitter had to say:
