Is oral biblical?

So my boyfriend (soon to be hubby) and I are in a long distance relationship (which means we're not physically together, yet). He wants to eat me out, and I want to make him feel good too. Is it against God if we want to do these things for each other? Some say it's okay as long as the couple is married. Others say that eating out/sucking his dong is not okay because that'd be ruining the God's temple (your body).

I really love my boyfriend and I want to follow God and His word. Am I able to or not?
