So my penis has the curve like a banana. I've read in various places that this can massage the g spot better in certain positions, but each site seems to say different positions. Any advice/ recommendations etc.
Missionary but with a pillow or something under her lower back/butt so that she's propped up. One of my faves is like if you did legs over shoulder missionary but you lay on your side. You can adjust the angle all the way to where your feet would be behind her head and hear feet would be in front of your face. So, just find the right angle that's good for your partner.
I have found that the best positions for this is missionary with a pillow under or off the edge of the bed to add additional leverage. Cowgirl is also quite amazing, hits just the right spot each time.
