Being eaten out feels...

Disappointing? As a 29 year old in my first and only long term (4 year) relationship I had high expectations for being able to be satisfied by my partner through oral sex despite being otherwise unable to cum through any other means. I have never had an orgasm in my life but I have been lead to believe that oral for women is supposed to feel amazing and if you have a partner willing to do it you are extremely lucky. Imagine my surprise when I received what in my mind is supposed to be the ultimate act for receiving pleasure and I feel nothing. I can't help but feel even more broken. Does anyone else not enjoy receiving oral? My partner often dismisses my never cumming as being in my head. Maybe not enjoying oral is in my head too or maybe it's his technique. I guess I'll never know.
