G-Spot?

I can seem to find and hit the G-Spot when I'm fingering my girl. But, not when were having sex. I've had a woman tell me that doggy style seems to work in hitting the G-spot but, I have not found that successful. I have also read where men who have a curved up shape in their penis have it easier when hitting it.

So my question is.. Is there any sex postions that work good for hitting the G-Spot?
