Vaginal orgasm

So I've had a lot of sex with quite a few guys and I have orgasmed countless times and it's been amazing. But my problem is I can only orgasm when my clit is being touched. Like if he's on top of me I need him both moving in and out but also pushed against me, I feel as though I'm having a mix of both types of orgasms. I say this because my orgasm is way more intense when he's moving in and out then when he's just eating me out. I know many women say that some women just can't have straight vaginal orgasms but I have done a lot of research on this and I've found that every women can, it's just harder for some. Any advice here?! Anyone else have this problem? Also, would this be an appropriate question to ask my gyno?
