Vaginal O

So...I have always had a hard time reaching orgasm. I have never been with a guy who was able to make me come on his own, maybe it was a communication issue, whatever. I've been married now for almost 9 years. I struggled with low libido until I switched from the pill to an IUD (Kyleena) about 8 months ago. My sex drive has increased tenfold, and I want to take charge of my sex life! My husband is the only man I have ever reached orgasm with during sex, but even then it was only clitoral, helped along with a vibrator. I know every woman is different, and it is possible that I may not be able to reach orgasm by vaginal stimulation alone, but I'll be damned if I'm not going to try. What do you ladies do to reach vaginal orgasm during intercourse? Any tips/techniques to offer?
