You state that you are a Christian...in a round about way by stating you want Christian views on the subject. You have a very good belief, contrary to what others might think, in not having sex until you are married. From this post and your previous posts I get the idea that "sex" to you is the actual insertion only. You can refer that to the "sex act" but sex involves foreplay and the various ways you can bring each other off.
In reading your previous posts I see a natural progression in your relationship. Your fist two posts dealt with you being concerned for your weight and how your boyfriend might view you. Next you were concerned with "dry sex" and getting pregnant. Then you jump to giving instructions on how to give oral sex. Next... You are getting to a point that is going to be hard to stop...for both of you. I know because I have been there. I was raised a Christian and still go to church. My wife (of 27 years) and I had the same beliefs when we met in College. We progressed in the same manner...only faster. It is hard to close Pandora's box once you have opened it. The feelings are there and playing with fire and teasing each other to the limit doesn't help the situation. I commend you on your beliefs and encourage you to stick to them. Don't let anyone talk you into going all the way because it is natural or feels good. What the two of you need to do is step back, look at your relationship, and see where it is now, where it is going, and where you want it to go. Because in my opinion you are not headed in the direction you want to go. Why do you think the Bible states in 1 Corinthians 7:1,2 "1 ...It is good for a man not to touch a woman. 2 Nevertheless, because of sexual immorality, let each man have his own wife, and let each woman have her own husband..."
