Thank you very much for taking your time to explain.

How do I perfect the oral sex techniques. While she likes what I do, it never got her close to an orgasm.

We have considered counselling on the affection being on different ways than we both would want it to be. In my mind if I get over the performance anxiety by being able to give her an orgasm, least a few times, I wouldnt worry much, thinking not having orgasms drives her, lack of affection.
Just do not know where to ask, what exactly to do.
