My husband and I have been married for two years. We have a relatively healthy sex life but he does not reciprocate with oral sex. When confronted, he said he has no issue surrounding it, he just feels it is not necessary. I feel rejected and that the focus is primarily on him reaching an orgasm, with no focus on my enjoyment. How can I have a conversation with him without him getting defensive? I have never had an orgasm through penetrative sex and, in previous relationships, I have loved receiving oral sex.
