Trust issues?

I really don't know what to say. I am in a long distance relationship and my bf would never even say anything like that to me about oral. We seriously would be broken up if he ever did anything like that. I know he trusts and respects me so he would never do anything to hurt me ever. You will know in your heart if he is cheating on you, you just have to listen and not doubt your heart because it won't lie to you.
