Like this description I've found on a womanshealthforum ?
"Before you penetrate her, massage her clit and labia with the head and shaft of your penis. Once inside, lift yourself up against her G-spot and then sink in deeply so the head of your cock goes under her cervix to her backstop, if you can reach that far. Hold yourself in balls deep, and then nudgefuck her deep spot without withdrawing, grinding against her clit at the same time. Stay high and in deep with her knees pulled up near her breasts. Gently bump her whole vulva and get your cock up inside her so that she can feel the head up in her gut and her heart, then increase the strength of your pounding as she loosens up and her deepest juices start to flow around your cock.
Gaze into her eyes and time it with her breathing so you are thrusting against her as she breaths out, making love to her where she lives in her deepest most intimate places.
It is such a great, emotional, deeply striking way to love her."
And about the never ending discussion that women can take large girths without problems because they can deliver babies, I think this post from a woman says it all :

I love her conclusion : "STOP TRYING TO MAKE YOUR COCKS COMPenis EnlargementTE WITH BABIES. It hurt's like a mother fucker to have one. We'd rather have a pleasurable experience and not be looking for something that came out of our vag that should be crying and have a head full of hair."
