Now that the cat's out of the bag about cervical orgasms, how do I achieve them?

I'm a 28 year old woman and I've never had a vaginal orgasm. I discovered that I can have clitoral orgasms with a vibrator by myself. That's worked fine for me for the past 8 years. <br><br>I've been in a relationship (monogamous) for 4 years now. My partner has tried the "come hither" move, we've tried different positions and he's tried with his finger but I can't seem to get there.<br><br>It's not that I haven't tried. I've had a lot of sex with him with no vaginal orgasm. It's like my body decides to just shut off the pleasure. <br><br>Now that women have shared the cervical orgasm "hack," I'm wondering if it's something I should try. Is it true for everyone women or just a few? Also, what is the best way to achieve a cervical orgasm with a penis? I've heard it's the "deep penetration" positions but we've tried that.
