Great news. Time to reflect on, and discuss your situation has brought you both to a positive outcome.
She has shared that she needed to bring up the question around vaginal sex to better understand what was on the table so to speak. I was able to make clear that I love her vagina - particularly performing oral sex on her, but that my "kink" is to only fuck her amazing ass - which I also love. She now also understands that this is neither a reflection (or rejection) of her femininity either - in fact it is an adoration & expansion of her femininity. Reading some posts also enlightened her to other views, reassured her we are not alone
I really think it can be hard for women to wrap their heads around this. Men are able to accept the concept of AO more easily and freely than women. That's why the subject needs to be raised sensitively and carefully - to avoid them drawing the wrong conclusion - ie rejection of their femininity. Seeing that there are many other couples doing the same thing (and happily) helps, which is one of the many things this site does to help others through what can be a challenging time.
I have been very focused on providing at least onevorgasm at each session. However, she explained that emotionally there are times she cannot orgasm (parenting, work stress, etc.) but she very much wants to be there for me and after reading a post from a member abt how his wife has given him permission to enter her ass while she's sleeping my wife requested undo this to her, explaining she might get into it & cum, or not - and that's just fine.
That's very kind of her! My wife suggested the same thing a long time ago, but it never worked out. She'd half wake up, and not being fully conscious she'd forget what she had promised and wanted to go back to sleep undisturbed. Good luck if you can make it work!
And those orgasms should start coming regularly. My wife usually has them in waves, so that there can be 3-5 each session. I think as she gets in to it your wife will find the same.
