The "A-spot" is the anterior fornix, a spot on the front wall of the vagina (a few inches past the G-spot) that's rumored to induce orgasm. To hit it, warm her up with plenty of foreplay. That'll help her uterus tip up, making it easier for you to reach the spot. Prop her hips up on a pillow, move into missionary position, and aim your thrusts high.

I been knowing about that spot...i didn't know it had a term for it though. I bet i can show that 'Doctor in Hoeing' a thing or two myself!
