Vaginal Orgasms

[Aquestionineedtoask]

I have never had a vaginal orgasm without clitoral stimulation, but recently I purchased a dildo, it was a thicker one, not anything huge, but definitely thicker, I decided to try it and had an orgasm by using the dildo alone. I’m not sure if it’s fluke, as it’s new, or whether the added thickness added to the fullness which helped me achieve a vaginal orgasm.
Has anyone else found it only possible to orgasm with a thicker dildo/penis?
I will try it again, but I’m not sure if it was the newness of a dildo, as I’ve never used one before, or if it was the extra fullness that reached that magical spot.

Could be fullness or could be angle or could be length. Depends on orgasm. G spot, cervical or friction.

During sex to achieve vaginal orgasm I need a larger penis, but I can also orgasm from being fingered. It's a precise position with his hooked fingers on my G spot.

Im the same, I can have a G spot orgasm with a dildo but not through PIV. DP is well endowed so that’s not the problem, but don’t know how to get the same feeling from him!
