As a woman I'm going to be really honest with you right now. I'm not going to pretend like your mother when you were young, or your wife or girlfriend does now. Size matters! A big penis will please a woman far more more than an average one. The mainstream media do not dare to touch the subject unless it's for cracking jokes but it is an important fact of life that women love guys who have a big penis and who know how to use it. As a sex expert I've helped countless couples and when I have one-on-one time with each partner to discuss issues the two most common things that come up regarding men are impotence and penis size. Because I'm a woman, women have no trouble confiding in me and telling me that their man simply is not big enough!
Why is this, you may ask. The reason is simple. A larger penis hits more nerves in the vagina that a smaller penis is ever capable of. Girth is of particular importance because if a thick penis enters the vagina then it hits the nerves close to the skin and deeper nerves because it's causing friction against the skin. Also length is important of course, but remember that the average depth of a vagina is between 5 and 6 inches. So the difference between a 7.5 and an 8.5 inch penis (in length) is probably only aesthetic – without your vagina is also very deep.
The average girth for a penis is between 4.5 – 5.5 inches. The average length is between 5.5 – 6.5 inches. However, in terms of girth, women can take far larger penalties than the average. If you have one of those far larger penalties then you'll have no trouble at giving your woman screaming, multiple orgasms without the need for clitoral stimulation.
If you have a smaller penis then the best way to make it feel bigger to her is to keep her legs closed. If she is lying down then put both of her leg over one shoulder. That way you'll feel bigger. Another way is lying her on her front and putting a pillow underneath her pubis section. Then, while keeping her legs closed, straddling her and entering her from behind.
If your length is small then 'doggy style' with her on all fours and you behind her should assist love-making as it will take your penis into her vagina. Another way is to get her on top, but in reverse, so she is facing away from you. This will make your penis feel very deep to her as it hits nerves that conventional sexual positions do not hit.
